ar71xx: Clear bits in ath79_setup_qca955x_eth_cfg

Browse Source 
Some u-boot versions for QCA955x set currently not cleared bits depending
on the used link speed. This breaks the rx/tx under OpenWrt. The mach-*.c
file is responsible to select the correct configuration bits and thus the
ath79_setup_qca955x_eth_cfg has to clear the unset.
