[PATCH v2] pinctrl: sh-pfc: r8a7791: add EtherAVB pin groups

[Sergei Shtylyov <sergei.shtylyov@xxxxxxxxxxxxxxxxxx>]

Add the EtherAVB pin groups to the R8A7791 PFC driver.

Also add the copyright for all the Cogent Embedded's past work on this file.

Signed-off-by: Sergei Shtylyov <sergei.shtylyov@xxxxxxxxxxxxxxxxxx>

---
The patch is against the 'devel' branch of Linus W.'s 'linux-pinctrl.git' repo.

Changes in version 2:
- added AVB_TX_ER pin to the AVB MII group;
- added Cogent Embedded's copyright;
- refreshed the patch.
