micrel: fix masking off LED bits

Browse Source 
Commit 20d8435a1c (phy: micrel: add of configuration for LED mode) made the
obvious mistake when masking off  the LED mode bits: forgot to do a logical NOT
to the mask with which it ANDs the register value, so that unrelated bits are
cleared instead.
