device: move is_domain0 and is_dev_on_domain0 to common code

Move is_domain0 and is_dev_on_domain0 from the Intel Xeon SP code to the
common coreboot code so that it can be used elsewhere in coreboot too,
and while moving also implement it as functions instead of macros which
is more in line with the rest of helper functions in that new file.
