[PATCH] iio: adc: max9611: Avoid implicit enum conversion warning

[Nathan Chancellor <natechancellor@gmail.com>]

Clang warns when an enumerated type is implicitly converted to another.

drivers/iio/adc/max9611.c:292:16: warning: implicit conversion from
enumeration type 'enum max9611_conf_ids' to different enumeration type
'enum max9611_csa_gain' [-Wenum-conversion]
                        *csa_gain = gain_selectors[i];
                                  ~ ^~~~~~~~~~~~~~~~~
1 warning generated.

Change the type of the variable 'gain_selectors' to int so that Clang
understands this is expected behavior.
