ath79: add patch to fix serial console and sysupgrade on OR750 (freif…

…unk-gluon#2512) 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.
