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.

Most tools used for compliance and SBOM generation use SPDX identifiers
This change brings us a step closer to an easy SBOM generation.

This driver supports both eDMA3 and eDMA4 (also referred to as DMA0 / DMA1
in some contexts..)
The IP blocks are almost identical, with sufficiently minor differences
to use them via a unified driver. The price is a great amount of code
obfuscation in the hardware description layer.
The original assumption was that the interrupt numbers are divided
so that 16 pins from 1 port are handled by a single interrupt source.
So source 0 would handle pins 0-15 and source 1 would handle pins 16-31.
This assumption is wrong, each pin has two sources, thus there are two
interrupt lines for each pin.
The driver uses source 0, and leaves source 1 disabled.
Adds support for NXP i.MX9-series System-on-Module chips.
- Support for i.MX93 is added
- CPU is Cortex A55 / ARMv8.2A
- The chip also contains a Cortex M33, but no support is provided
- Supported drivers include lpuart only for now
