The ag71xx driver from Linux 5.4 currently has various shortcomings
when used with OpenWrt compared to our downstream version.
For example, the upstream driver does not support modifying the ethernet
clock and configuring RGMII delays on the MAC side.
While we should certainly switch to the upstream driver, the amount of
necessary patches would make it cumbersome to work with. It's also
highly likely we won't be able to finish patching the upstream driver in
time for a Linux 5.4 release.
Tested on Siemens WS-AP3610.

* Sync the patches with the changes done for kernel 4.19
* Use KERNEL_TESTING_PATCHVER
* Refresh the configuration
* Fix multiple compile bugs in the patches
* Only add own ag71xx files for kernel 4.19 and use upstream version for
5.4.

While converting Nanostation M XW from current ar71xx code to ath79 I've
hit one issue, where the ethernet networking wasn't working, so I was
checking every bit in the networking setup path between ar71xx and
ath79.
I've came to the following code in ar71xx/mach-ubnt-xm.c:
static void __init ubnt_xw_init(void) {
...
ath79_setup_ar934x_eth_cfg(AR934X_ETH_CFG_MII_GMAC0 |
AR934X_ETH_CFG_MII_GMAC0_SLAVE);
...
}
Where this code is setting AR934X_ETH_CFG_MII_GMAC0_SLAVE bit in
AR934X_GMAC_REG_ETH_CFG register, but I couldn't find a way of setting
this bit from DTS, so this patch adds `mii-gmac0-slave` DTS property
which allows setting of this bit in `gmac-config`, which is then used in
Nanostation M XW DTS.
