Samsung pinctrl DTS and driver changes for v5.18

Conversion of Samsung pinctrl bindings to dtschema followed up with
alignment of DTS files to the dtschema.

The entire work consists of three parts but everything should be merged
at once to avoid dtschema check errors:
1. Samsung pinctrl driver change necessary to accept new DTS (driver
   depends on node names and this has to be adjusted because of dtschema).
2. Conversion to dtschema which brings requirement of different naming
   of the GPIO nodes.
3. DTS commits depending on driver (1) above, which convert all GPIO pin
   bank names to new naming, required by dtschema.
   This also includes few cleanups around DTS which are here to avoid
   any merge conflicts.

The Samsung pinctrl driver changes are backwards compatible.  However
the DTS changes (renaming nodes) could cause problems in out-of-tree or
other project implementations of the driver.
