This patchset adds support for the Oxford Semiconductor OX820 SoC Pinctrl
registers along he OX810 Pinctrl support.
The GPIO control registers are common enough to leave the code untouched.

Add refactoring to move ox810se specific functions into specific ops structures
an add support for the dt match data to get soc specific structures.

Add support for the Oxford Semiconductor OX820 which is similar as OX810 but
has 50 pins and two registers banks to setup alternate functions.
Add specific pins, groups and functions structures.
Add DT match data to select corresponding support.
