Subject: [PATCH v3 04/10] pinctrl: cy8c95x0: Remove redundant check in cy8c95x0_regmap_update_bits_base()

The function is never called with the PORTSEL register in the argument.
Drop unneeded check, but rescue a comment. While at it, drop inline
and allow any compiler to choose better stragy (note, that inline in
C code is only a recomendation to most of the modern compilers anyway).
