This PRs goal is to update the M Core section for i.MX8MP for PD26.1.0.

Due to (breaking) changes in the mcu section, preserve the existing
section by moving it to the release doc files.

The script in the mcuxsdk directory overrides the ARMGCC_DIR variable,
so remove sourcing the script from the doc.
Also, the path of where to find the examples is not quite correct,
appears to be due to a rename. Update the path.
Add a cd command for easier step-by-step instructions.
Since the introduction of standard boot for U-Boot, the
"clk-imx8mp.mcore_booted" kernel command line parameter is no longer
added via a U-Boot command. Change to optargs.

Wouldn't it be more pretty, to rename the old file to something like mcu.A0.rsti and put the content of the new mcu.rsti into a file called something like mcu.head.rsti?

Like this we would not have to paste the complete text in all older manuals.

You'd have lots of A0, A1, A2, ... files. Also not that pretty; especially when you keep in mind that this rule would apply to all other shared content, even the one that changes frequently.

I like the paste rule we have now, imo it has more/better upsides than downsides.
