ath79: add patch to fix serial console and sysupgrade on OR750 (#2512)

Browse Source 
The serial console on the Joy-IT OR750i doesn't work, because the UART
node is disabled in device tree. This also breaks sysupgrade.

The issue is already fixed upstream in OpenWRT by
7054721cf94f4aa8fe71ac4c28c922b19a69ba1d ("ath79: enable UART in SoC
DTSI files"), but since 19.07 doesn't support the OR750, we need our own
patch.

Subject: ath79: Joy-IT OR750i: fix UART
The serial console defaults to disabled in the DTSI files, explicitly
enable it for the Joy-IT OR750i, so we can get a console in linux.
