refactor(build): distinguish BL2 as TF-A entry point and BL2 running at EL3
BL2_AT_EL3 is an overloaded macro which has two uses:
1. When BL2 is entry point into TF-A(no BL1)
2. When BL2 is running at EL3 exception level
These two scenarios are not exactly same even though first implicitly
means second to be true. To distinguish between these two use cases we
introduce new macros.
BL2_AT_EL3 is renamed to RESET_TO_BL2 to better convey both 1. and 2.
Additional macro BL2_RUNS_AT_EL3 is added to cover all scenarious where
BL2 runs at EL3 (including four world systems).
BREAKING CHANGE: BL2_AT_EL3 renamed to RESET_TO_BL2 across the
repository.

fix(zynqmp): conditional reservation of memory in DTB
When the TF-A is placed in DDR memory range, the DDR memory range is
getting explicitly reserved in the default device tree by TF-A.
This creates an error condition in the use case where Device tree is
not present or it is present at a different location.
To fix this, a new build time parameter, XILINX_OF_BOARD_DTB_ADDR, is
introduced. The TF-A will reserve the DDR memory only when a valid
DTB address is provided to XILINX_OF_BOARD_DTB_ADDR during build.
Now the user has options, either manually reserve the desired
DDR address range for TF-A in device tree or let TF-A access and modify
the device tree, to reserve the DDR address range, in runtime using
the build parameter.
refactor(auth): use a single function for parsing extensions
Previously, extensions were parsed twice: once with error checking for
validation, and a second time without error checking to extract the

A simpler approach is to have get_ext() be responsible for all extension
parsing, and to treat a NULL OID as an indicator that get_ext() is only
being called for validation. cert_parse() checks that get_ext() returns
IMG_PARSER_OK and fails otherwise.

feat(imx8mq): add workaround code for ERR11171 on imx8mq
This new workaround takes advantage of the per core IMR
registers in GPC in order to unmask the IRQ0, still generated
by the 12bit in IOMUX_GPR register (which now remains always set),
so it can only wake up one core at the time.Also, this entire
workaround has now been moved here in TF-A, allowing the kernel
side to be minimal.
Another advantage this workaround brings is the removal of the
50us delay (which was necessary before in gic_raise_softirq in
kernel) by allowing the core that is waking up to mask his own
IRQ0 in the suspend finish callback.
One important change here is the way the cores are woken up in
dram_dvfs_handler. Since the wake up mechanism has changed from
asserting the 12th bit in IOMUX_GPR and leaving the IMR1 1st bit
on for each core to exactly the reverse, that is, leaving the
IOMUX_GPR 12th bit always set and then masking/unmasking the IMR1
1st bit for each independent core, we need to use the imx_gpc_core_wake
to wake up the cores.
Also, the 50us udelay is moved to TF-A (inside imx_pwr_domain_off)
from kernel(gic_raise_softirq), since the new cpuidle workaround
does not need it in order to clean the IOMUX_GPC 12bit. For now,
the udelay seems to be still needed in order to delay the affinity
info OFF for the dying core. This is something that needs further
investigation.
