spi: bfin_spi6xx: Remove unnecessary test for bus and pins[bus]
For invalid bus number, current code returns NULL in the default case of
switch-case statements. In additional, pins[bus] is always not NULL because
it is the address of specific row of the two-dimensional array.
Thus this patch removes these unnecessary test.
