Subject: [PATCH v2] dt-bindings: iio: adc: Add ROHM BD79100G

The ROHM BD79100G is a 12-bit ADC which can be read over SPI. Device has
no MOSI pin. ADC results can be read from MISO by clocking in 16 bits.
The 4 leading bits will be zero, last 12 containig the data.

Device has only VCC supply pin, which acts also as a VFS, determining the
voltage for full 12-bits. Specifying it is mandatory.

This seems identical to the ti,ads7866.

Support ROHM BU79100G using ti,ads7866 as a fallback.

Revision history:
v1 => v2:
 - Support BU79100G using ti,ads7866 as a fallback to avoid duplicated
   driver code.
