Subject: [PATCH] staging: iio: light: isl29028: fix correct mask value

The mask value in the read_raw/write_raw is absolute
value, not the bit position value.
Fixing this in the implemented function to check value,
not with the bit position value.

Somehow this was missed on my testing.
I tested today again with linux next and found this issue.
