    iio: adc: rockchip_saradc: fix bitmask for channels on SARADCv2
    
    [ Upstream commit b0a4546df24a4f8c59b2d05ae141bd70ceccc386 ]
    
    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).
