bdf76faa3e 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.

ebcce35be4 ar71xx: Use PHY fixups for Open Mesh MR900
The delays of PHY/MAC on the MR900 are done by u-boot and OpenWrt in
different ways. u-boot only modifies the ETH_CFG of the QCA955x based on
the link speed. But OpenWrt can only modify the PHY delays based on the
link speed.

This can lead to communication problems when u-boot initializes the ETH_CFG
for a specific link speed (e.g. 10BASE-T) but then OpenWrt the sets the PHY
delays to an incompatible value.

Instead reset the ETH_CFG delay bits of the QCA955x to a specific value and
only rely on the AT803x PHY settings.

22c5f96c6b ar71xx: Allow to set the RXDV, RXD, TXD, TXE delays for QCA955x
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.
