ssb: PCI revision ID register is 8-bit wide
The SSB code reads PCI revision ID register as 16-bit entity while the register is actually 8-bit only (the next 8 bits are the programming interface register). Fix the read and make the 'rev' field of 'struct ssb_boardinfo' 8-bit as well, to match the register size. Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: John W.
