Subject: [RESEND PATCH v3 0/3] pinctrl: Adding support for Microchip/Microsemi serial GPIO controller

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

The driver now register two separate banks (per instance), one for
input pins (the first) and one for output direction. This eliminates
the need for specifying the direction as part of the gpio
arguments. The (fixed) direction is thus inherent from the gpio
handle.

v3 changes:
- Renamed all usage of "mchp" abbrevation with "microchip".
- Split the in/output directions into (two) separate banks.
- Eliminated the bindings include file (from above)
- Changed SPDX license to "GPL-2.0-or-later"
- Change -ENOTSUPP to -EOPNOTSUPP
- Minor type/symbol naming changes

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
