Revert "ar71xx: Clear bits in ath79_setup_qca955x_eth_cfg"

Browse source 
Not all mach-* files set all boards correctly in ETH_CFG. They depend on
some preset values by u-boot which were not previously modified by
ath79_setup_qca955x_eth_cfg. Avoiding to modify them in this function keeps
it backward compatible for these boards.

This reverts commit 119b8ab2c2eac237ec4e9c4d0ed53df22b5c6978.
