Don't build ME linux kernel modules (not currently packed)

[tlaurion]

MEI is removed because the HECI devices are disabled on all Librems (all either have HAP bit or neutralized ME).

AFAICT, there also are no boards actually setting CONFIG_LINUX_MEI in the board config (so mei.ko/mei-me.ko are never actually bundled), and I don't see any logic to insert those modules if they were bundled. So I don't think =m makes sense for the other Linux configs either.

Right checked linux configs, linux module and board statements.

Some boards's linux config compile as kernel modules:

CONFIG_INTEL_MEI=m
CONFIG_INTEL_MEI_ME=m
CONFIG_INTEL_MEI_TXE=m

Where modules/linux:

# ME drivers for talking the the management engine
linux_modules-$(CONFIG_LINUX_MEI)       += drivers/misc/mei/mei.ko
linux_modules-$(CONFIG_LINUX_MEI)       += drivers/misc/mei/mei-me.ko

But where no boards configs actually include CONFIG_LINUX_MEI. Basically an old artifact of older times where ME got investigated to be neutered/deactivated/removed. I think we should add verification of platform runtime somehow with at least cbmem to check runtime ME state in another issue? @JonathonHall-Purism ?

Maybe in the system info screen would be a reasonable place for something like this?
