clk: at91: fix update bit maps on CFG_MOR write

commit 263eaf8f172d9f44e15d6aca85fe40ec18d2c477 upstream.

The regmap update bits call was not selecting the proper mask, considering
the bits which was updating.
Update the mask from call to also include OSCBYPASS.
Removed MOSCEN which was not updated.
