Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs include three
12-Bit successive approximation A/D converters.
RZ/T2H has two ADCs with 4 channels and one with 6.
RZ/N2H has two ADCs with 4 channels and one with 15.
Add support for them.
V2:
* pick up Reviewed-by from Geert
* dt-bindings: move required after patternProperties
* dt-bindings: describe 16 channels, but limit per-SoC to 6 / 15
* dt-bindings: use uppercase for clock descriptions
* remove max-channels property and find it from parsed channel subnodes
* remove start/stop wrappers
* stop calibration even on failure
* move data reading to rzt2h_adc_read_single() instead of interrupt
* handler
