Message

The series add support for the serial GPIO controller used by
Microchip Sparx5, as well as (MSCC) ocelot/jaguar2 SoCs.

This is the second revision of the patch series.

v2 changes:
- Adds both in and output modes.
- Use direct adressing of the individual banks (#gpio-cells = <4>),
  also osoleting need for addressing macros in bindings include file.
- Property 'microchip,sgpio-ports' (uint32, bitmask) replaced by
  proper range set (array of [start,end]) 'microchip,sgpio-port-ranges'.
- Fixes whitespace issues in Kconfig file
