Add support for two-byte RES probes

Browse Source 
Some chips implement the RES (0xab) opcode, but they use a non-standard
two byte response instead of the usual one byte response. A two-byte
response has the accuracy of REMS and RDID, so don't check for REMS/RDID
availability before running a two-byte RES.

Corresponding to flashrom svn r1017.
