soc/intel/alderlake: Update cpu and pch tracehub modes

The patch gets the cpu and pch's tracehub mode from the debug area
of the Descriptor Region and updates the respective UPDs.

TEST=Build, verify the tracehub mode values.

Update CPU' and PCH's Trace Hub modes:
	img=coreboot.rom
	printf '\x01' | dd of=$img bs=1 seek=3841 count=1 conv=notrunc
	printf '\x01' | dd of=$img bs=1 seek=3842 count=1 conv=notrunc

Check coreboot logs:
    [DEBUG]  rt_debug: CPU TraceHub Mode: 1 PCH Tracehub Mode: 1
