[PATCH] sh_eth: disable -Woverride-init warning

[Arnd Bergmann]

-Woverride-init is part of a 'make W=1' build and it might be nice
to enable it in normal builds as it catches real bugs, but it
causes hundreds of identical false positive warnings in the sh_eth
driver:

ethernet/renesas/sh_eth.c:63:11: error: initialized field overwritten [-Werror=override-init]
ethernet/renesas/sh_eth.c:63:11: note: (near initialization for 'sh_eth_offset_gigabit[0]')
ethernet/renesas/sh_eth.c:64:11: error: initialized field overwritten [-Werror=override-init]
ethernet/renesas/sh_eth.c:64:11: note: (near initialization for 'sh_eth_offset_gigabit[1]')
ethernet/renesas/sh_eth.c:65:12: error: initialized field overwritten [-Werror=override-init]
ethernet/renesas/sh_eth.c:65:12: note: (near initialization for 'sh_eth_offset_gigabit[2]')
ethernet/renesas/sh_eth.c:66:12: error: initialized field overwritten [-Werror=override-init]
ethernet/renesas/sh_eth.c:66:12: note: (near initialization for 'sh_eth_offset_gigabit[3]')
ethernet/renesas/sh_eth.c:67:11: error: initialized field overwritten [-Werror=override-init]
ethernet/renesas/sh_eth.c:67:11: note: (near initialization for 'sh_eth_offset_gigabit[4]')

This turns off the particular warning for this file, overriding the
C flags.
