[PATCH] sh-pfc: r8a7794: add SDHI pin groups

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

From: Shinobu Uehara <shinobu.uehara.xc@renesas.com>

Add SDHI0/1/2 pin groups to R8A7794 PFC driver.

Signed-off-by: Shinobu Uehara <shinobu.uehara.xc@renesas.com>
[Sergei: renamed SD data pins to match the driver, rebased, renamed, added
changelog.]
Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

The patch is against the 'devel' branch of Linus W.'s 'linux-pinctrl.git' repo
plus  the R8A7794 PFC support patch posted last week and the R8A7794 MMCIF pin
group patch posted this week.
