rtc: map CMOS index 0x37 to 0x32 on read and writes
QEMU's attempt to implement the century byte cover two possible places
for the byte. A common one on modern chipsets is 0x32, but QEMU also
stores the value in 0x37 (apparently for IBM PS/2 compatibility---it's
only been 25 years). To simplify the implementation of the century
byte, store it only at 0x32 but remap transparently 0x37 to 0x32 when
reading and writing from CMOS.
