Synchronise arch.h and arch_helpers.h with TF-A-Tests ...

The headers forked at some point in the past and have diverged a lot. In
order to make it easier to share code between TF-A-Tests and TF-A, this
patch synchronises most of the definitions in the mentioned headers.

This is not a complete sync, it has to be followed by more cleanup.

This patch also removes the read helpers for the AArch32 instructions
ats1cpr and ats1hr (they are write-only).

    mmc: poll eMMC status after EXT_CSD command

    EXT_CSD command needs to access data from eMMC device. Add the
    operation of polling eMMC device status. Make sure the command is
    finished.

A hacked delay time can't fit each eMMC device. Since the above commit
enables the polling operation, remove the hacked delay time now.

juno: Add romlib support ...

This patch adds support to build a combined BL1
and ROMLIB binary file with the right page
alignment in Juno. When USE_ROMLIB=1 is set for
Juno, it generates the combined file
bl1_romlib.bin which needs to be used instead of
bl1.bin

romlib: Allow patching of romlib functions ...

This change allows patching of functions in the
romlib. This can be done by adding "patch" at the
end of the jump table entry for the function that
needs to be patched in the file jmptbl.i.
Functions patched in the jump table list will be
built as part of the BL image and the romlib
version will not be used

Revert "aarch32: Apply workaround for errata 813419 of Cortex-A57" ...

This reverts commit 6f512a3.

According to the 'Cortex-A57 MPCore Software Developers Errata Notice':

    This bug will only affect secure AArch64 EL3. If the above
    conditions occur, the CPU will not invalidate the targeted EL3 TLB
    entries and incorrect translations might occur.

For this reason it is not needed in AArch32.

xlat v2: Support mapping regions with allocated VA ...

Provide new APIs to add new regions without specifying the base VA.

- `mmap_add_region_alloc_va` adds a static region to mmap choosing as
  base VA the first possible address after all the currently mapped
  regions. It is aligned to an appropriate boundary in relation to the
  size and base PA of the requested region. No attempt is made to fill
  any unused VA holes.

- `mmap_add_dynamic_region_alloc_va` it adds a region the same way as
  `mmap_add_region_alloc_va` does, but it's dynamic instead of static.

- `mmap_add_alloc_va` takes an array of non const `mmap_region_t`,
  maps them in the same way as `mmap_add_region_alloc_va` and fills
  their `base_va` field. A helper macro has been created to help create
  the array, called `MAP_REGION_ALLOC_VA`.

rpi3: add RPI3_USE_UEFI_MAP build option ...

The default Raspberry Pi 3 memory mapping for ATF is geared towards
the use of uboot + Linux. This creates issues when trying to use
ATF with an UEFI payload and Windows on ARM64.

We therefore introduce new build option RPI3_USE_UEFI_MAP, that
enables the build process to use an alternate memory mapping that
is compatible with UEFI + Windows (as well as UEFI + Linux).
