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.

MMU initialization is redundant for bootloaders(BL2) that load TF‑A(BL31).
TF-A will ignore and overwrite any MMU configuration performed by BL2.
Additionally the MMU comes with a large memory footprint (~50 KB)
which could be precious for such setups.
When the MMU is disabled all the memory is treated as device memory and
all alignment faults generate exceptions (as opposed to normal memory when
MMU is enabled). For that reason we need to add -fno-builtin when compiling
with CONFIG_ARCH_USE_MMU != y to prevent alignment faults.
- Guard MMU initialization with CONFIG_ARCH_USE_MMU
- If CONFIG_ARCH_USE_MMU is not set add -fno-builtin which prevents alignment errors.
- Deliberately didn't try to replace CONFIG_ARCH_HAVE_MMU with CONFIG_ARCH_USE_MMU
occurrences, because this will break a lot of build targets that assume MMU without
guarding the MMU initialization.

This adds support for the i.MX9 ROMAPI, allowing boot in a more
device agnostic and portable manner. The ROMAPI "natively" allows to:
- Query the boot device for information.
- Copy data from the boot device to RAM.
An extra functionality was added to ROMAPI to calculate
offsets of sequential AHAB containers.
The AHAB functionality is built on top of raw ELE primitives and allows to:
- Authenticate a container image.
- Release the authenticated container.

Add kernel build (target imx93-evk:knsh) to i.MX93 EVK.
This target is preconfigured for use with AHAB boot (see
https://spsdk.readthedocs.io/en/latest/examples/ahab/imx93/imx93_ahab_uboot.html)
as a replacement of U-Boot proper (BL33 at EL2), hence
the load address is set to 0x80200000.

`boot_stage_puts` used by early asm calls arm64_lowputc() for each
character in a loop. During that loop it uses x1 as the pointer to
the next character to be printed. However, x1 is clobbered by
arm64_lowputc(), resulting in undefined behaviour (only the first
character of the string is guaranteed to be printed).
Fix this by using x19 instead.

The changes include:
- Removing duplicate #include directives that were present in the same file
- Consolidating includes that were split across multiple lines unnecessarily
- Removing unused includes that were no longer needed
- Fixing some formatting issues with includes
The changes improve code organization and maintainability by:
- Reducing unnecessary dependencies
- Making include dependencies more explicit
- Following consistent include patterns
- Removing dead code
No functional changes are made - this is purely a code cleanup commit.

Before the MPU initialization, the up_update_task(this_cpu()) function is called at a time when hardware cache coherency is not yet enabled.
In certain critical scenarios, Core 1 reads a zero value for tcb from the global variable g_assignedtask and stores this zero value into the tpidr
register. This results in subsequent interrupt handlers reading a zero tcb, causing an exception.
