regulator: s2mps11: fix pctrlsel macro usage in s2mpg10_of_parse_cb()

Commit 979dd8da76eb ("regulator: s2mps11: add S2MPG11 regulator")
incorrectly ended up using macros for S2MPG10 in the S2MPG11 case. They
happen to end up giving the same result, but for clarity, the correct
macros should be used.

No functional change.
