[PATCH 2/2] pinctrl: sh-pfc: r8a7794: add audio clock pin groups

[Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>]

From: Ryo Kataoka <ryo.kataoka.wt@renesas.com>

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.]
