Add a DTS binding for the MediaTek Audio Front End device, and
definitions for the in-tree devices.
These .dts files were auto-generated from pre-existing SOF code (that
defined the devices as C structs) using a tool currently being
submitted in the SOF tree, thus are included here as separate files.
The expectation is that future variants will be authored in this
format directly. Longer term we can move them directly into the core
board DTS.

Add Zephyr support for the Audio DSP on the MT8196 SOC. This is a
very similar device to previous designs. Most of this patch is just
DTS.
The biggest delta is the more complicated second level interrupt
controller, though it is still able to be represented using some
vaguely clever DTS config over the older intc_mtk_adsp driver.
Also the memory layout is slightly different, requiring a little
indirection to set the initial boot stack address and log output
buffer. And the timer "irq_ack" register bits moved.
