Log Message:
wii: rtcsram: Ignore counter bias when reading/writing RTC.

Counter bias is used by system menu as an offset from the RTC for the
time displayed in the Wii's OS. Since Wii doesn't have a concept of time
zones, this bias is useless to us.

Due to a previous bug with parsing SRAM data, the bias read was always 0.
Now that the bias is read correctly, we're reading and writing
preposterous times -- remove the bias from the calculation to restore
the previous setting.

So with this change, the RTC is always in UTC and the Wii system menu
date/time settings adjusts the bias as an offset from that.
