scratchpad registers used by pinctrl pull configuration.

[Severity: Low]
This isn't a bug, but should the word "add" be capitalized here to follow
the MFD subsystem naming conventions?

[Severity: Medium]
Will older dtschema tools skip validation for this new compatible string?

It appears this compatible string was omitted from the select block earlier
in the file, which is required for compatibility with dtschema <2024.02:

select:
  properties:
    compatible:
      contains:
        enum:
          ...
          - altr,sdr-ctl
          - amd,pensando-elba-syscon

Should ambarella,cv75-sec-scratchpad also be added to this enum block so
older tools correctly select and apply this schema?
