Staging: iio: use the BIT macro in adc
This patch replaces bit shifting on:
0,1,2, and 3 with the BIT(x) macro.
Issue addressed by checkpatcg.pl.
This was done with the help of Coccinelle:

constant int g;
@@
(
0<<\(x\|g\)

3<<\(x\|g\)
)
@script:python b@

coccinelle.y = int(g2) + 1

-(3 << g)
+(BIT(y)| BIT(g))
