iio: light: tsl2563: Drop unused defintion(s)

Browse source

The CALIB_FRAC() is defined and might had been used in
tsl2563_calib_from_sysfs(). But let's just move a comment
from it to the latter function.

CLAIB_FRAC_HALF is used in a single place, i.e. in
tsl2563_calib_to_sysfs(). So, let's just inline it there.

While at it, switch to use DIV_ROUND_CLOSEST().
