clk: rs9: Fix DIF OEn bit placement on 9FGV0241
[ Upstream commit 29d861b5d29b6c80a887e93ad982cbbf4af2a06b ]
On 9FGV0241, the DIF OE0 is BIT(1) and DIF OE1 is BIT(2), on the other
chips like 9FGV0441 and 9FGV0841 DIF OE0 is BIT(0) and so on. Increment
the index in BIT() macro instead of the result of BIT() macro to shift
the bit correctly on 9FGV0241.
