synquacer: Enable MMU using xlat_tables_v2 library

BL31 runs from SRAM which is a non-coherent memory on synquacer. So
enable MMU with SRAM memory marked as Non-Cacheable and mark page tables
kept on SRAM as Non-Cacheable via XLAT_TABLE_NC flag. Also add page tables
for Device address space.

Adding ULL as requested. I used ULL() macros for BL*_{BASE,LIMIT}

uniphier: allocate xlat region of on-chip SRAM only when needed

Currently, the xlat region of the on-chip SRAM is always allocated
for all BL images.

The access to the on-chip SRAM is necessary for loading images from
a USB memory device (i.e. when updating firmware), so unneeded for
the usual boot procedure.

To avoid this waste, allocate the xlat region dynamically only for
BL2, and only when it is necessary.

uniphier: get back original BL31/32 location used before BL2-AT-EL3

Commit 247fc0435191 ("uniphier: switch to BL2-AT-EL3 and remove BL1
support") accidentally changed the location of BL31 and BL32. The
new memory map overlaps with the audio DSP images, also gives impact
to OP-TEE. They are both out of control of ARM Trusted Firmware, so
not easy to change. This commit restores the image layout that was
originally used prior to the BL2-AT-EL3 migration.

uniphier: set PROGRAMMABLE_RESET_ADDRESS to disable warm boot mailbox

The warm boot mailbox code is compiled if PROGRAMMABLE_RESET_ADDRESS
is disabled.

The warm boot mailbox is useless for UniPhier SoC family because BL1
is not the first image. The UniPhier platform implements non-TF ROM,
then BL1 works as a pseudo ROM, so it is never executed in the warm
boot.

The reset vector address is not actually programmable for UniPhier
platform, but it should not hurt to enable PROGRAMMABLE_RESET_ADDRESS
to disable the mailbox and remove pointless plat_get_my_entrypoint.
