My last commit to fix profile mode displays on AMD platforms caused
an issue on Intel platforms - sorry!

In it I was reading the current functional mode (MMC, PSC, AMT) from
the BIOS but didn't account for the fact that on some of our Intel
platforms I use a different API which returns just the profile and not
the functional mode.

This commit fixes it so that on Intel platforms it knows the functional
mode is always MMC.

I also fixed a potential problem that a platform may try to set the mode
for both MMC and PSC - which was incorrect.

Tested on X1 Carbon 9 (Intel) and Z13 (AMD).
