Document Renesas RZ/G2UL ADC bindings. RZ/G2UL ADC is almost identical
to RZ/G2L, but it has 2 analog input channels compared to 8 channels
on the RZ/G2L.

v3->v4:
* Removed unnecessary SoC specific reg description as it is
equivalent to the logic used in reg.
* Removed Items from reg.
v2->v3:
* Added generic description for reg.
* Improved schema validation by restricting both channel and reg to [0-1].
v1->v2:
* Started using generic compatible for RZ/G2UL and added SoC specific validation
for channels.
