Subject: [PATCH 3.15 10/61] sh_eth: fix SH7619/771x support

3.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sergei Shtylyov <sergei.shtylyov@...entembedded.com>

[ Upstream commit d8b0426af5b67973585712c9af36b86f6ea97815 ]

Commit 4a55530f38e4 (net: sh_eth: modify the definitions of register) managed
to leave out the E-DMAC register entries in sh_eth_offset_fast_sh3_sh2[], thus
totally breaking SH7619/771x support.  Add the missing entries using  the data
from before that commit.
