[PATCH v4] pinctrl: sh-pfc: r8a7794: add VIN pin groups

[Sergei Shtylyov <sergei.shtylyov@xxxxxxxxxxxxxxxxxx>]

From: Koji Matsuoka <koji.matsuoka.xm@xxxxxxxxxxx>

Add VIN0/1 pin groups to R8A7794 PFC driver.

Sergei:  rebased, renamed, added changelog, gathered 12  VIN1 data pins into
a single pin group, added "vin1_data10" pin group, used 'union vin_data' and
VIN_DATA_PIN_GROUP() macro to describe VIN1 pins, reversed the order of  the
VIN1 pin groups, removed unneeded empty lines, fixed  VIN1 separator comment.

The patch  is against the 'devel' branch of Linus W.'s 'linux-pinctrl.git' repo.
It depends on the patch moving 'union vin_data'  to shared header file in order
to build.

Changes in version 4:
- made use of the 'union vin_data' and VIN_DATA_PIN_GROUP() macro to describe
  the VIN1 pins;
- listed the VIN1 data pin groups in reverse order;
- removed  empty lines before VIN0/1 pin data;
- fixed the VIN1 separator comment.

Changes in version 3:
- added "vin1_data10" pin group.

Changes in version 2:
- relied on the 'struct vin_data' and #define VIN_DATA_PIN_GROUP() moved to the
  common header file;
- added to the VI1_DATA8/9/10/11 pin group VI1_DATA[0-7] pins and renamed/moved
  this pin group.
