iio: chemical: sps30: Explicity truncate constant by masking

When breaking up a constant to write to two 8 bit registers
it isn't obvious to sparse that it was intentional.

CHECK   drivers/iio/chemical/sps30.c
drivers/iio/chemical/sps30.c:120:30: warning: cast truncates bits from constant value (8004 becomes 4)

So in the interests of minimising noisy warnings, let us add
a mask.
