ar71xx: Use private version of ath79_setup_qca955x_eth_cfg for MR900 

The MR900 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 MR900 can be used instead.
