nxp: imx8/imx8x: switch to native Zephyr drivers and timer domain

LaurentiuM1234 · LaurentiuM1234 · commit 206ce15c7bfe · 2024-04-18T14:23:42.000+03:00
This commit includes all necessary changes for switching
to timer domain and Zephyr native drivers on imx8 and imx8x.
This consists of:
	1) Switching all imx8 topologies to timer domain.
	2) Disabling Zephyr DMA domain
	3) Various interrupt-related fixes via Kconfig-related
	ifdef logic.

This commit includes all necessary changes for switching
to native Zephyr drivers on imx8/imx8x.
