BL31 binary size is aligned to 4KB because of the
code in include\plat\arm\common\arm_reclaim_init.ld.S:
__INIT_CODE_UNALIGNED__ = .;
. = ALIGN(PAGE_SIZE);
__INIT_CODE_END__ = .;
with all the zero data after the last instruction of
BL31 code to the end of the page.
This causes increase in size of BL31 binary stored in FIP
and its loading time by BL2.
This patch reduces the size of BL31 image by moving
page alignment from __INIT_CODE_END__ to __STACKS_END__
which also increases the stack size for secondary CPUs.

Currently only single signing domain is supported for SP packages but
there is plan to support dual signing domains if CoT is dualroot.
SP_CONTENT_CERT_ID is the certificate file which is currently generated
and signed with trusted world key which in-turn is derived from Silicon
provider RoT key.
To allow dual signing domain for SP packages, other certificate file
will be derived from Platform owned RoT key.
This patch renames "SP_CONTENT_CERT_ID" to "SIP_SP_CONTENT_CERT_ID" and
does other related changes.

Currently, 'SMCCC_ARCH_FEATURES' SMC call handler unconditionally
returns 'SMC_OK' for 'SMCCC_ARCH_SOC_ID' function. This seems to
be not correct for the platform which doesn't implement soc-id
functionality i.e. functions to retrieve both soc-version and
soc-revision.
Hence introduced a platform function which will check whether SMCCC
feature is available for the platform.
Also, updated porting guide for the newly added platform function.

It is desired to have the peripheral writes completed to clear the
interrupt condition and de-assert the interrupt request to GIC before
EOI write. Failing which spurious interrupt will occurred.
A barrier is needed to ensure peripheral register write transfers are
complete before EOI is done.
GICv2 memory mapped DEVICE nGnR(n)E writes are ordered from core point
of view. However these writes may pass over different interconnects,
bridges, buffers leaving some rare chances for the actual write to
complete out of order.
GICv3 ICC EOI system register writes have no ordering against nGnR(n)E
memory writes as they are over different interfaces.
Hence a dsb can ensure from core no writes are issued before the previous
writes are *complete*.
