Boards that run the i.MX9 bootloader at EL1 must not touch EL3-only
configuration. Add Kconfig guards so that:
* DDR training (IMX9_DDR_TRAINING)
* FIQ decode support (ARM64_DECODEFIQ)
are selected only when ARCH_ARM64_EXCEPTION_LEVEL == 3.
Code in arm64_chip_boot() is also guarded with ARCH_ARM64_EXCEPTION_LEVEL == 3

On rt10xx chips the MPU didn't got reset, which is needed for use
with bootloaders. Furthermore the TCM sizes where fixed now we use
kconfig symbol to set the size respectively. Also we mark ITCM as
RO/RO so we can't change data we executed from.
The up_saveusercontext function leverages USER_SAVE macro,
which is ordinarily used as a first half of the context switch.
This macro is therefore unsuitable to be used standalone,
it pops return address from the stack and does not return.
This patch adds missing instructions to do what would otherwise
be done by the second half of the context switch.
Tested by compiling and verifying the disassembly - the function
no longer falls through to the next function in the program memory,
push/pop instructions are balanced and stack contents preserved

This implements an interrupt-based SPI driver for the BCM2711 SPI
interfaces (excluding auxiliary SPI interfaces). Only tested on SPI0
since proprietary firmware does not initialize any other SPI interfaces,
and doing so will require reverse engineering.

Interrupts should be disabled during the access to the user signature
area in internal flash memory, otherwise the system might be halted.
This applies also for read operation as this is performed with a
special flash commands on a special part of memory.

Fix some misspelled field names.
These field names seem to be used only in private contexts.
Thus, the probability of external code accessing these fields is very
low.
In the rare case of external usage, compile time errors will easily
direct users to the new field name.
Properly select physical bank for block erase based on block number.
Previously, it would configure flash erase bank select based on the logical bank. If banks were swapped, and user application
tried to erase the first block of logical bank 2 (expecting to erase starting at 0x08100000), it would actually erase starting
at 0x0800000. This is fixed in this commit.

After a mailing list suggestion, the indirection that enabled
ARCH_TOOLCHAIN_GCC only when user requested it is removed.
The indirection was a safety measure for chips and boards with linker
scripts that (possibly) do not handle keeping for example .vectors
section even if the linker considers it unreferenced.
Instead, all existing configurations now disable
CONFIG_DEBUG_OPT_UNUSED_SECTIONS to prevent the linker from removing
any code. (Preserving previous behaviour.) This can be removed again
at some point after making sure that corresponding linker script
only removes code that is truly unused.

Even when enabled, the PCNT counter doesn't accumulate into the 32-bit value.
Instead, a value in range [PCNT_LOW_LIMIT, PCNT_HIGH_LIMIT] is always returned.
This is due to interrupt events associated with limit overflows are disabled on the periphery,
therefore the ISR responsible for the accumulation never gets called.
Fixed by enabling the associated interrupt events.
