TSP: Support multi-threading CPUs on FVP

Commit 11ad8f20

 added supporting
multi-threaded CPUs on FVP platform, including modifications for
calculating CPU IDs. This patch imports the strong definition of the
same CPU ID calculation on FVP platform for TSP.

Without this patch, TSP on FVP was using the default CPU ID calculation,
which would end up being wrong on CPUs with multi-threading.

Fix MAP_REGION for GCC 4.9

Since commit 769d65da ("xlat: Use MAP_REGION macro as compatibility
layer"), building with GCC 4.9 fails.

Taking into account that MAP_REGION(_FLAT) is widely used in array
initializers, do not use cast.

For Trusted Board Boot, BL1 RW section and BL2 need more space to
support the ECDSA algorithm. Specifically, PLAT_ARM_MAX_BL1_RW_SIZE
is increased on ARM platforms.

And on the Juno platform:
    - BL2 size, PLAT_ARM_MAX_BL2_SIZE is increased.
    - SCP_BL2 is loaded into the space defined by BL31_BASE ->
      BL31_RW_BASE. In order to maintain the same size space for
      SCP_BL2,PLAT_ARM_MAX_BL31_SIZE is increased.

The type `unsigned long` is 32 bit wide in AArch32, but 64 bit wide in
AArch64. This is inconsistent and that's why we avoid using it as per
the Coding Guidelines. This patch changes all `UL` occurrences to `U`
or `ULL` depending on the context so that the size of the constant is
clear.

This problem affected the macro `BIT(nr)`. As long as this macro is used
to fill fields of registers, that's not a problem, since all registers
are 32 bit wide in AArch32 and 64 bit wide in AArch64. However, if the
macro is used to fill the fields of a 64-bit integer, it won't be able
to set the upper 32 bits in AArch32.

By changing the type of this macro to `unsigned long long` the behaviour
is always the same regardless of the architecture, as this type is
64-bit wide in both cases.

Some Tegra platform files have been modified by this patch.

In the S-EL1&0 translation regime we aren't using the higher VA range,
whose translation table base address is held in TTBR1_EL1. The bit
TCR_EL1.EPD1 can be used to disable translations using TTBR1_EL1, but
the code wasn't setting it to 1. Additionally, other fields in TCR1_EL1
associated with the higher VA range (TBI1, TG1, SH1, ORGN1, IRGN1 and
A1) weren't set correctly as they were left as 0. In particular, 0 is a
reserved value for TG1. Also, TBBR1_EL1 was not explicitly set and its
reset value is UNKNOWN.

Therefore memory accesses to the higher VA range would result in
unpredictable behaviour as a translation table walk would be attempted
using an UNKNOWN value in TTBR1_EL1.

On the FVP and Juno platforms accessing the higher VA range resulted in
a translation fault, but this may not always be the case on all
platforms.

This patch sets the bit TCR_EL1.EPD1 to 1 so that any kind of
unpredictable behaviour is prevented.

This bug only affects the AArch64 version of the code, the AArch32
version sets this bit to 1 as expected.

Use a mmap_region_t as parameter instead of getting a parameter for each
structure member. This reduces the scope of changes when adding members
to mmap_region_t.

Also align on the convention of using mm_cursor as a variable name for
the currently inspected region when iterating on the region array.

plat/arm: Fix BL31_BASE when RESET_TO_BL31=1

The value of BL31_BASE currently depends on the size of BL31. This
causes problems in the RESET_TO_BL31 case because the value of
BL31_BASE is used in the model launch parameters, which often changes.

Therefore, this patch fixes BL31_BASE to the middle of Trusted SRAM,
to avoid further model parameter changes in future.

Use the MAP_REGION to build the mmap_region_t argument in wrappers like
mmap_add_region(). Evolution of the mmap_region_t might require adding
new members with a non-zero default value. Users of MAP_REGION are
protected against such evolution. This commit also protects users of
mmap_add_region() and mmap_add_dynamic_region() functions against these
evolutions.

Also make the MAP_REGION macro implementation more explicit and make it
a mmap_region_t compound literal to make it useable as a function
parameter on its own and to prevent using it in initialization of
variables of different type.
