openwrt for the rock64

[wilsonYan]

for anyone interested these are the basic kernel patches:
the change to the ethernet node could probably go upstream

Hello again ! I've recently put together a new build.

CHANGES OF NOTE:

* Latest glibc / 5.10 kernel / openwrt packages
* Reworked the ethernet node in the DTS file ! (no more weird load problem and network restarts are possible without issue !)
* Led functionality is now enabled and configurable from GUI
* Small change copied from ayufan for power.
* Small xhci change lifted from git.kernel.org

TODO: 

* Release the patches I have that make this build  (see above post for the main kernel patches)
* Possibly get sound and display working
* Possibly add more packages/support for things like qos

OUTSTANDING:

* Asix ax88179 adapter is still unreliable for me  when plugged directly into the usb3 port. It appears to be much better when plugged into a usb3 hub (I haven't been able to crash it yet though i'm not sure this driver has ever been reliable when using bridging vendor or no vendor)

* I've switched the realtek r8152 driver to the vendor driver. The rtl8156 (2.5gbps) may stil be unreliable or only operate in 1gbps mode though.
