iio: adc: ad7124: Micro-optimize channel disabling
The key objective in ad7124_disable_one() is clearing the
AD7124_CHANNEL_EN_MSK bit in the channel register. However there is no
advantage to keep the other bits in that register because when the
channel is used next time, all fields are rewritten anyhow. So instead
of using ad7124_spi_write_mask() (which is a register read plus a
register write) use a simple register write clearing the complete
register.
Also do the same in the .disable_all() callback by using the
.disable_one() callback there.
