dt-bindings: iio: adc: rockchip-saradc: Fix RV1106 compatible

Browse Source 
rockchip,rv1106-saradc was folded into the fallback enum together
with rockchip,rk3576-saradc, falling back to rockchip,rk3588-saradc.
The two IP blocks are not equivalent, though: per the RV1106 TRM v0.3,
chapter 20 (SAR-ADC), RV1106 only has 2 channels at 10-bit resolution,
versus 8 channels at 12-bit on RK3588. Documenting it as falling back
to rk3588-saradc allows device trees that would bind against the wrong
channel table and report an incorrect voltage scale.

Remove rockchip,rv1106-saradc from the RK3588 fallback enum and give
it its own standalone compatible entry, matching the dedicated match
table entry added by the driver patch.
