Subject: [PATCH 1/3] iio: adc: rockchip_saradc: fix bitmask for channels on
 SARADCv2

From: Quentin Schulz <quentin.schulz@...obroma-systems.com>

The SARADCv2 on RK3588 (the only SoC currently supported that has an
SARADCv2) selects the channel through the channel_sel bitfield which is
the 4 lowest bits, therefore the mask should be GENMASK(3, 0) and not
GENMASK(15, 0).

Fixes: 757953f8ec69 ("iio: adc: rockchip_saradc: Add support for RK3588")
