ar71xx: Use private version of ath79_setup_qca955x_eth_cfg for MR1750
The MR1750 must unset some bits in ETH_CFG which were set by u-boot to work correctly under OpenWrt. But the global function ath79_setup_qca955x_eth_cfg will not unset all of them to increase the backward compatiblity with older mach-* files. A private (simplified) version for MR1750 can be used instead. Signed-off-by: Sven Eckelmann <sven.eckelmann@open-mesh.com> SVN-Revision: 49070
