UPSTREAM: sb/intel/{bd82x6x,ibexpeak}: Fix out of bounds access in intel_me_status()

On Ibex Peak (and maybe also on other platforms), when the AltMeDisable
bit is set (-S or -s option of me_cleaner), the ME PCI device disappears
from the bus and its configuration space is all ones.

This causes a freeze in intel_me_status(), as coreboot tries to access
an out of bounds array element.
