[pcbios] Add additional sanity check for bogus e820 map
At POST time some BIOSes return invalid e820 maps even though
they indicate that the data is valid. We add a check that the first
region returned by e820 is RAM type and declare the map to be invalid
if it is not.
This extends the sanity checks from 8b20e5d ("[pcbios] Sanity-check
the INT15,e820 and INT15,e801 memory maps").
