ath79: update WA/XC devices UBNT_VERSION to 8.5.3
Ubiquiti WA devices with newer hw version 2011K require UBNT_VERSION
to be at least 8.5.3, otherwise the image is rejected:
New ver: WA.ar934x.v8.5.0-42.OpenWrt-r10947-
65030d81f3
Versions: New(525568) 8.5.0, Required(525571) 8.5.3
Invalid version 'WA.ar934x.v8.5.0-42.OpenWrt-r10947-
65030d81f3'
For consistency, also increase version number for XC devices.
