ar71xx: fix ethernet on wnr2000-v4
Most people report broken ethernet with upstream. Last year, user "franz.flasch"
authored a working mach-file. His patch is outdated so I modernized it. Original
patch and user commentary on page 1:
https://forum.openwrt.org/viewtopic.php?pid=260861#p260861
I have figured out what the critical differences are between the two that caused
upstream ethernet to break.
1) Both ath79_init_mac() functions calls must be invocated before any GMAC init
2) must init GMAC0 before GMAC1
That was enough to get upstream to function, but I wanted to enjoy my confidence
having tested franz's patch for a week sucessfully, so I put his whole
function in, which only features more differences in order of function calls.
An expert should consider these changes, which could pose potential bugs/issues:
1) No longer using the flag AR934X_ETH_CFG_SW_PHY_SWAP in the
ath79_setup_ar934x_eth_cfg() call.
2) Possible consequence of no longer explicitly setting ethernet duplex/speed.
Review: With this patch, my ethernet and wireless works.
