The patch series adds the support for adc102s021 and family.

The family of devices are easier to
support since they all (no matter the resolution) seem to respond in
12-bits with the LSBs set to 0 for the reduced resolution devices.

Changes in v3:
Patch 1:
- No changes in dt-bindings

Patch 2:
- used be16_to_cpu() for the endian conversion.
- used config index enum while setting up the adc128_config[]

Changes in v2:
Patch 1:
- No changes in dt-bindings

Patch 2:
- Arranged of_device_id and spi_device_id in numeric order.
- Used enum to index into adc128_config.
- Reorder adc128_config in alphabetical.
- Include channel resolution information.
- Shift is calculated per resolution and used in scaling and
raw data read.
