staging/xgifb: Replace XGI340_CR6B table with simple if/else
The XGI340_CR6B lookup table consists of the entries
{0xaa, 0xaa, 0xaa, 0xaa} for an index <= 2 and
{0x00, 0x00, 0x00, 0x00} for all other indices.
The only user XGINew_SetDRAMDefaultRegister340 loops over these 4 values
of a line with a for loop and since all entries are the same for each line
we can simply replace the whole lookup table with a simple if/else assignment.
