io: block: fix block_read/write may read/write overlap buffer

The block operations were trying to optimize the number of memory
copies, and it tried to use directly the buffer supplied by the user
to them. This was a mistake because it created too many corner cases:

1- It was possible to generate unaligned
   operations to unaligned buffers. Drivers that were using
   DMA transfer failed in that case.

2- It was possible to generate read operations
   with sizes that weren't a multiple of the block size. Some
   low level drivers assumed that condition and they calculated
   the number of blocks dividing the number of bytes by the
   size of the block, without considering the remaining bytes.

3- The block_* operations didn't control the
   number of bytes actually copied to memory, because the
   low level drivers were writing directly to the user buffer.

This patch rewrite block_read and block_write to use always the device
buffer, which the platform ensures that has the correct aligment and
the correct size.

Enable SVE for Non-secure world

This patch adds a new build option, ENABLE_SVE_FOR_NS, which when set
to one EL3 will check to see if the Scalable Vector Extension (SVE) is
implemented when entering and exiting the Non-secure world.

If SVE is implemented, EL3 will do the following:

- Entry to Non-secure world: SIMD, FP and SVE functionality is enabled.

- Exit from Non-secure world: SIMD, FP and SVE functionality is
  disabled. As SIMD and FP registers are part of the SVE Z-registers
  then any use of SIMD / FP functionality would corrupt the SVE
  registers.

The build option default is 1. The SVE functionality is only supported
on AArch64 and so the build option is set to zero when the target
archiecture is AArch32.

This build option is not compatible with the CTX_INCLUDE_FPREGS - an
assert will be raised on platforms where SVE is implemented and both
ENABLE_SVE_FOR_NS and CTX_INCLUDE_FPREGS are set to 1.

Also note this change prevents secure world use of FP&SIMD registers on
SVE-enabled platforms. Existing Secure-EL1 Payloads will not work on
such platforms unless ENABLE_SVE_FOR_NS is set to 0.

Additionally, on the first entry into the Non-secure world the SVE
functionality is enabled and the SVE Z-register length is set to the
maximum size allowed by the architecture. This includes the use case
where EL2 is implemented but not used.

ARM platforms: Fixup AArch32 builds

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.

Implement support for the Activity Monitor Unit on Cortex A75

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.

Replace macro ASM_ASSERTION with macro ENABLE_ASSERTIONS

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.
