[PATCH 2/2] net: ethernet: renesas: sh_eth: don't open code of_device_get_match_data()

[Wolfram Sang]

From: Wolfram Sang <wsa+rene...@sang-engineering.com>

This change will also make Coverity happy by avoiding a theoretical NULL
pointer dereference; yet another reason is to use the above helper function
to tighten the code and make it more readable.

Signed-off-by: Wolfram Sang <wsa+rene...@sang-engineering.com>

Tested on a Lager board.
