sb/amd/sb800: Remove bit shift that does nothing
This bit shift attempts to set bits 8 and 9 of the byte variable (counting
from 0). However, as the name suggests, this variable is only 8 bits
wide, so the shift does nothing. Reading section 7.5 of the
AMD SB800-Series Southbridges Register Programming Requirements manual,
bits 8 and 9 are already set by default, so we can remove the bit shift.
(Alternatively, we could try setting the corresponding bits one byte
higher in 0xF1 if needed.)
