Add wistron oem command to detect riser-f

PNOR needs to know whether riser-f is present when poweron, so we add
an oem command to detect whether riser-f is present.
The result will return two bytes of data, the first byte is bus9 and
the second byte is bus10.

Return data will have 0x00 or 0x01.
0x00 means riser-f not present
0x01 means riser-f present
