Some u-boot versions for QCA955x change the delays based on the link speed
during boot. This usually breaks the support of other linkspeeds when
OpenWrt is booted. It also conflicts with the
at803x_platform_data::fixup_rgmii_tx_delay. OpenWrt has to set its own
values in QCA955X_GMAC_REG_ETH_CFG.
The default RGMII values from the Atheros u-boot are currently used to
preset the existing mach files. These may have to be adjusted for boards
using different values but which are not currently set them explicitely in
OpenWrt.

SVN-Revision: 49029
The ETH_RXDV_DELAY (17:16) and ETH_RXD_DELAY (15:14) are currently not cleared
by the function ath79_setup_ar934x_eth_cfg. Clearing these in the
ath79_setup_ar934x_eth_cfg may cause problems on some hardware because they
rely on the preset value by the bootloader.
Instead another function is introduced which also works on ETH_CFG on AR934x.
It can be used to safely clear and set ETH_RXDV_DELAY and ETH_RXD_DELAY on
machines which require special settings.
