[PATCH] pinctrl: sh-pfc: r8a77970: add QSPI pins, groups, and functions

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

From: Dmitry Shifrin <dmitry.shifrin@cogentembedded.com>

Add the QSPI{0|1} pins/groups/functions to the R8A77970 PFC driver.

[Sergei: ported to the upstream driver, fixed up the swapped QSPI0 SPCLK/
SSL pins, fixed up the comments, moved the QSPI pins/groups/functions to
be in the alphanumeric order, removed unneeded empty lines, renamed the
patch.]
