[PATCH 6/8] iio: adc: rzt2h: Prepare for SoCs with different ADC info

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>

Prepare the driver for RZ/V2H(P) support, where the ADC supports 8-bit and
12-bit conversion modes with channel configurations that differ from
RZ/T2H.

Allow each SoC to provide its own IIO info structure and use the
chip-specific configuration when registering the IIO device.
