If AACRH32_SP is not specified, it causes the DEFAULT_LINKER_SCRIPT
variable to be empty, and then the linker takes the variable following
it as if it was the linker script, which is not one. This patch
addresses that issue by requiring the AARCH32_SP variable to be set
before continuing.

Switch from IMX_BOOT_UART_BASE=0 to IMX_BOOT_UART_BASE=auto to make it
more obvious that the detection is based on the runtime autodetection.
In addition this moves the evaluation of IMX_BOOT_UART_BASE into the
makefile which removes the ugly conditional compilation as well.

Provide a helper to detect the enabled UART device during runtime. This
lower the integration effort and make it more straight forward for
'simple' use-cases with a single UART enabled. If multiple UARTs are
enabled the first enabled is returned.
The auto-detection is enabled by setting IMX_BOOT_UART_BASE=0 to keep
the backward compatibility. For more advanced use-cases (multiple UARTs
are enabled) the user still has to provide the correct base address.

Starting with GCC >= 12.x the -Wall option includes -Werror=array-bounds
checks. Per default GCC treats all memory accesses below 4096 as NULL,
so access to ROMAPI causes the following warning:

------------
This comes arguably from us somewhat abusing pointers to access MMIO
memory regions, which is not really covered by the C language.
Replace the pointer-dereferencing mmio_read_8() with an implementation
that uses inline assembly, to directly generate an 8-bit load
instruction. This avoids the compiler thinking that this access is using
a pointer it needs to jealously look after.

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.

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.

When performing a software driven MR access, the following
sequence must be done automatically before performing other
APB register accesses:
1. Set MRCTRL0.mr_wr=1
2. Check for MRSTAT.mr_wr_busy=0. If not, go to step (2)
3. Check for MRSTAT.mr_wr_busy=0 again (for the second time),
if not, go to step (2).
