The block size of some storage device is 4096-byte long, such as UFS. But
PARTITION_BLOCK_SIZE is defined as 512-byte long. So replace it by
PLAT_PARTITION_BLOCK_SIZE. Make it configurable in platform.

This patch provides the following features and makes modifications
listed below:
- Individual APIAKey key generation for each CPU.
- New key generation on every BL31 warm boot and TSP CPU On event.
- Per-CPU storage of APIAKey added in percpu_data[]
  of cpu_data structure.
- `plat_init_apiakey()` function replaced with `plat_init_apkey()`
  which returns 128-bit value and uses Generic timer physical counter
  value to increase the randomness of the generated key.
  The new function can be used for generation of all ARMv8.3-PAuth keys
- ARMv8.3-PAuth specific code placed in `lib\extensions\pauth`.
- New `pauth_init_enable_el1()` and `pauth_init_enable_el3()` functions
  generate, program and enable APIAKey_EL1 for EL1 and EL3 respectively;
  pauth_disable_el1()` and `pauth_disable_el3()` functions disable
  PAuth for EL1 and EL3 respectively;
  `pauth_load_bl31_apiakey()` loads saved per-CPU APIAKey_EL1 from
  cpu-data structure.
- Combined `save_gp_pauth_registers()` function replaces calls to
  `save_gp_registers()` and `pauth_context_save()`;
  `restore_gp_pauth_registers()` replaces `pauth_context_restore()`
  and `restore_gp_registers()` calls.
- `restore_gp_registers_eret()` function removed with corresponding
  code placed in `el3_exit()`.
- Fixed the issue when `pauth_t pauth_ctx` structure allocated space
  for 12 uint64_t PAuth registers instead of 10 by removal of macro
  CTX_PACGAKEY_END from `include/lib/el3_runtime/aarch64/context.h`
  and assigning its value to CTX_PAUTH_REGS_END.
- Use of MODE_SP_ELX and MODE_SP_EL0 macro definitions
  in `msr	spsel`  instruction instead of hard-coded values.
- Changes in documentation related to ARMv8.3-PAuth and ARMv8.5-BTI.

cpu_idx is used as mix of `unsigned int` and `signed int` in code
with typecasting at some places. This change is to unify the
cpu_idx as `unsigned int` as underlying API;s `plat_my_core_pos`
returns `unsigned int`

Support for PKCS#1 v1.5 was deprecated in SHA 1001202d and fully removed
in SHA fe199e3b

, however, cert_tool is still able to generate
certificates in that form. This patch fully removes the ability for
cert_tool to generate these certificates.

Additionally, this patch also fixes a bug where the issuing certificate
was a RSA and the issued certificate was EcDSA. In this case, the issued
certificate would be signed using PKCS#1 v1.5 instead of RSAPSS per
PKCS#1 v2.1, preventing TF-A from verifying the image signatures. Now
that PKCS#1 v1.5 support is removed, all certificates that are signed
with RSA now use the more modern padding scheme.

cert_tool is now able to accept a command line option for specifying the
key size. It now supports the following options: 1024, 2048 (default),
3072 and 4096. This is also modifiable by TFA using the build flag
KEY_SIZE.

Previously, TF-A could not support large RSA key sizes as the
configuration options passed to MBEDTLS prevented storing and performing
calculations with the larger, higher-precision numbers required. With
these changes to the arguments passed to MBEDTLS, TF-A now supports
using 3072 (3K) and 4096 (4K) keys in certificates.

Some of the platform (ie. Agilex) make use of CCU IPs which will only be
initialized during bl2_el3_early_platform_setup. Any operation to the
cache beforehand will crash the platform. Hence, this will provide an
option to skip the data cache invalidation upon bl2 entry at EL3

Some cores support only AArch64 from EL1 and above, e.g. A76, N1 etc. If
TF-A is compiled with CTX_INCLUDE_AARCH32_REGS=0 so as to properly
handle those cores, only the AArch64 cores' assembly is included in the
TF-A binary. In other words, for FVP, TF-A assumes that AArch64 only
cores will never exist in the same cluster with cores that also support
AArch32.

However, A55 and A75 can be used as AArch64 only cores, despite
supporting AArch32, too. This patch enables A55 and A75 to exist in
clusters together with AArch64 cores.

This patch adds support for the Undefined Behaviour sanitizer. There are
two types of support offered - minimalistic trapping support which
essentially immediately crashes on undefined behaviour and full support
with full debug messages.

The full support relies on ubsan.c which has been adapted from code used

Add __dead2 to match the header declaration and C definition.

I also changed '__dead2 void' to 'void __dead2' for the consistency
