Update Xilinx maintainer details

ARM Power State Coordination Interface (ARM DEN 0022D) chapter
6.5 "Recommended StateID Encoding" defines the state ID which can be
used by platforms. The recommended power states can be presented by
below values; and it divides into three fields, every field has 4 bits
to present power states corresponding to core level, cluster level and
system level.

  0: Run
  1: Standby
  2: Retention
  3: Powerdown

This commit changes to use upper recommended power states definition on
Hikey960; and changes the power state validate function to check the
power state passed from kernel side.

Introduce AArch64 Raspberry Pi 3 port

Previously the cache flush happened in 2 different places in code
depending on whether TRUSTED_BOARD_BOOT is enabled or not. This
patch unifies this code path for both the cases. The `load_image()`
function is now made an internal static function.

This port can be compiled to boot an AArch64 or AArch32 payload with the
build option `RPI3_BL33_AARCH32`.

Note: This is not a secure port of the Trusted Firmware. This port is
only meant to be a reference implementation to experiment with an
inexpensive board in real hardware.

Fix issues for AArch32 builds on ARM platforms

The bl2_early_platform_setup() and bl2_platform_setup() were
redefined for Juno AArch32 eventhough CSS platform layer had
same definition for them. The CSS definitions definitions were
previously restricted to EL3_PAYLOAD_BASE builds and this is now
modified to include the Juno AArch32 builds as well thus
allowing us to remove the duplicate definitions in Juno platform
layer.

This patch fixes a couple of issues for AArch32 builds on ARM reference
platforms :

1. The arm_def.h previously defined the same BL32_BASE value for AArch64 and
   AArch32 build. Since BL31 is not present in AArch32 mode, this meant that
   the BL31 memory is empty when built for AArch32. Hence this patch allocates
   BL32 to the memory region occupied by BL31 for AArch32 builds.

   As a side-effect of this change, the ARM_TSP_RAM_LOCATION macro cannot
   be used to control the load address of BL32 in AArch32 mode which was
   never the intention of the macro anyway.

2. A static assert is added to sp_min linker script to check that the progbits
   are within the bounds expected when overlaid with other images.

3. Fix specifying `SPD` when building Juno for AArch32 mode. Due to the quirks
   involved when building Juno for AArch32 mode, the build option SPD needed to
   specifed. This patch corrects this and also updates the documentation in the
   user-guide.

4. Exclude BL31 from the build and FIP when building Juno for AArch32 mode. As
   a result the previous assumption that BL31 must be always present is removed
   and the certificates for BL31 is only generated if `NEED_BL31` is defined.

When defining different sections in linker scripts it is needed to align
them to multiples of the page size. In most linker scripts this is done
by aligning to the hardcoded value 4096 instead of PAGE_SIZE.

This may be confusing when taking a look at all the codebase, as 4096
is used in some parts that aren't meant to be a multiple of the page
size.

The Cortex A75 has 5 AMU counters.  The first three counters are fixed
and the remaining two are programmable.

A new build option is introduced, `ENABLE_AMU`.  When set, the fixed
counters will be enabled for use by lower ELs.  The programmable
counters are currently disabled.

SPM fixes

Support ARMv7 architectures

Flush the affinity data in psci_affinity_info

This patch replaces the macro ASM_ASSERTION with the macro
ENABLE_ASSERTIONS in ARM Cortex-A53/57/72 MPCore Processor
related files. There is build error when ASM_ASSERTION is set
to 1 and ENABLE_ASSERTIONS is set to 0 because function
asm_assert in common/aarch32/debug.S is defined in the macro
ENABLE_ASSERTIONS but is called with the macro ASM_ASSERTION.

There is also the indication to use ENABLE_ASSERTIONS but not
ASM_ASSERTION in the Makefile.
