fiptool: Enable Visual Studio build

Add APIs to get and modify attributes of memory regions

uniphier: fix section of  ROTPK hash

Update Foundation, AEM and Cortex Models versions

Fix use of MSR (immediate)

Trusted Firmware has been tested as part of its CI system against Cortex
and Foundation models in the 11.1 Model release available on
developer.arm.com. Trusted Firmware has also been tested against the
v8.7 AEM model.  This patch updates the user guide documentation to
reflect the version of the Foundation, AEM and Cortex Models that
Trusted Firmware has been tested against.

This is not executable code.  It should be put into .rodata instead
of .text section.

This produces more correct BL1 image when SEPARATE_CODE_AND_RODATA is
defined.

docs: Update Trusted Board Boot Requirements document number

Init and save / restore of PMCR_EL0 / PMCR

Update PSCI to v1.1

Updates are required to enable the fiptool utility to be built on a
Windows platform.  This change modifies the source files to enable
building with Visual Studio (detected via preprocessor settings).
The primary changes are:
  1.  Provide an implementation of the getopt_long function.  This does
      not exist in the Visual Studio CRT libraries because Windows
      commands normally use '/' not '-' as an option indicator.
  2.  Redirect some function names to match those supported by the
      Visual Studio libraries (when building with Visual Studio).
  2.  Modify a structure name (stat) to match that provided
      by the Visual Studio libraries (_stat).

Note - this change does not provide makefile updates.  It only modifies
       the sources to enable the fiptool to be built from a Visual
       Studio project.  In normal use the presence of FIPTOOL.EXE is
       enough to satisfy the make requirements.  A makefile change may
       be derived from the Visual Studio command line information at
       some point in the future.

This patch introduces a new API in the translation tables library
(v2), that allows to change the memory attributes of a memory
region. It may be used to change its execution permissions and
data access permissions.

As a prerequisite, the memory must be already mapped. Moreover, it
must be mapped at the finest granularity (currently 4 KB).

Previously, in AArch32, `IMAGE_XLAT_DEFAULT_REGIME` wasn't defined. The
translation regime is only used in the AArch64 port of the translation
tables library v2, so this is not a problem for now, but future patches
will use it.

`IMAGE_EL` isn't used in AArch32, so it isn't needed to define it.

Integration of reset2 PSCI v1.1 functionality

The macro DEFINE_SYSREG_WRITE_CONST_FUNC defines an inline function
to an assembly statement that uses the MSR (immediate) instruction
to access the PSTATE.  The "i" (immediate) assembly constraint on
the operand was only satisfied when compiling with optimizations
enabled which resulted in the function being optimized out - the
"const uint64_t v" parameter was optimized out and replaced by a
literal value.

When compiling without optimizations, the function call remained and
therefore the parameter is not optimized out - compilation fails as
the constraint is impossible to satisfy by the compiler.

This patch replaces the function encapsulating the use of
the MSR (immediate) with a macro that allows the literal value to be
directly fed to the inline assembly statement

Currently TF does not initialise the PMCR_EL0 register in
the secure context or save/restore the register.

In particular, the DP field may not be set to one to prohibit
cycle counting in the secure state, even though event counting
generally is prohibited via the default setting of MDCR_EL3.SMPE
to 0.

This patch initialises PMCR_EL0.DP to one in the secure state
to prohibit cycle counting and also initialises other fields
that have an architectually UNKNOWN reset value.

Additionally, PMCR_EL0 is added to the list of registers that are
saved and restored during a world switch.

Similar changes are made for PMCR for the AArch32 execution state.

NOTE: secure world code at lower ELs that assume other values in PMCR_EL0
will be impacted.

This patch implements PSCI_SYSTEM_RESET2 API as defined in PSCI
v1.1 specification. The specification allows architectural and
vendor-specific resets via this API. In the current specification,
there is only one architectural reset, the warm reset. This reset is
intended to provide a fast reboot path that guarantees not to reset
system main memory.

Increase PLAT_ARM_MMAP_ENTRIES and MAX_XLAT_TABLES

The MEM_PROTECT support adds a MMAP region for DRAM2, which when
building with TBBR support and OP-TEE tsp requires an additional
entry in the MMAP region array in BL2 - PLAT_ARM_MMAP_ENTRIES is
increased.

The MEM_PROTECT support also adds a new region in BL31, and when
BL31 is placed in DRAM, the memory mappings require an additional
translation table - MAX_XLAT_TABLES is increased.
