block: Handle "rechs" and "large" translation options
Sure, CHS translation is an obscure topic, and legacy options for
hard-disk geometries are obscure as well. But since QEMU does nothing
with it except telling the BIOS, and since there "large" and "rechs"
are listed in the enums, parsing them seems to be the bare minimum.
