[PATCH 1/2] pinctrl: sh-pfc: r8a7794: add SSI pin groups

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

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

Add the SSI pin groups to the R8A7794 PFC driver.

[Sergei: fixed inconsistent alternate pin group naming, split SSI5/6 pin
groups into data/control ones, moved SSI7 data B group to its proper place,
fixed  pin names in  the comments to *_pins[], extended Cogent Embedded's
copyright, added the changelog, renamed the patch.]
