Adding support for Microchip family of 153.6 ksps, Low-Noise 16/24-Bit
Delta-Sigma ADCs with an SPI interface. This driver covers the following part
numbers:
 - MCP3561, MCP3562, MCP3564, MCP3561R, MCP3562R, MCP3564R,
 - MCP3461, MCP3462, MCP3464, MCP3461R, MCP3462R and MCP3464R.

Differences related to previous patch:

v2:
- fix review comments:
  - change the device tree bindings
  - change the ADC channel creation (starting from DT)
  - use defines, masks and FIELD_PREP() instead of hardcoded values
  - mode the PGA from Hardware Gain to scale
  - add a current output channel from burnout current
  - fix coding style issues
  - use self explanatory naming to drop the comment
- renumbered the versioning (start with v1 instead of v0)

v1:
- first version comitted to review
