[PATCH 2/3] iio: adc: ad7192: Fix internal/external clock selection

[Fabrizio Lamarque <fl.scratchpad@xxxxxxxxx>]

Fixed wrong selection of internal clock when mclk is defined.

Resolved a logical inversion introduced in c9ec2cb328e3.

Fixes: c9ec2cb328e3 iio: adc: ad7192: use devm_clk_get_optional() for mclk
