hwmon: (lm75) Fixup tmp75b clr_mask

commit a95a4f3f2702b55a89393bf0f1b2b3d79e0f7da2 upstream.

The configuration register of the tmp75b sensor is 16bit long, however
the first byte is reserved, so there is not no need to take care of it.

Because the order of the bytes is little endian and it is only necessary
to write one byte, the desired bits must be shifted into a 8 bit range.
