nxp: imx8ulp: change SOC name to MIMX8UD7

The SOC name `imx8ulp` has been just a placeholder until
support for the SOC's ADSP (since this is the only core
that's supported in Zephyr) could be added to the NXP HAL.
Now that the support has been added, to make use of it, the
SOC name `imx8ulp` has to be changed to `mimx8ud7`. As such,
this commit does the following:
	1) Introduces SOC part number configuration - needed
	by some HAL headers.
	2) Replaces all occurrences of `imx8ulp` (as the SOC
	name) with `mimx8ud7`.
	3) Enables `CONFIG_HAS_MCUX`.
	4) Aligns all `CONFIG_SOC_` configurations with the
	new SOC name.
	5) Updates SOF hash. This is needed to fix build issues
	caused by this name change. This is not done in a separate
	commit to preserve bisectability.
