[Buildroot] [git commit branch/2019.11.x] board/lemaker/bananapro: fix wlan module

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=d17c8b06c94c3ceaa1f66ae3193ebf00b4840e41
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2019.11.x

Restore a patch which disables 00B IRQ for the built-in wlan module which
allows working wlan module again.  It turned out that it shouldn't have been
deleted because the bug still exists in the mainline linux kernel, so keep
this patch the same as armbian[1] to have wifi connection working correctly.
