Subject: [PATCH net-netx] net: renesas: sh_eth: suppress initialized field overwritten warning

Suppress a bunch of warnings of the form:

drivers/net/ethernet/renesas/sh_eth.c:100:13: warning: initialized field overwritten [-Woverride-init]

This is because after the sh_eth_offset_xxx array is initialized to SH_ETH_OFFSET_INVALID,
some specific register_offsets are re-initialized. It wasn't a mistake.
