pinctrl: sh-pfc: r8a7794: Add audio clock pin groups

Add the audio clock pin groups to the R8A7794 PFC driver.

[Sergei:  fixed pin group names to reflect the reality, fixed pin names in
the comments to *_pins[], lowercased the separator comment, resolved rejects,
added the changelog, renamed the patch.]
