[Buildroot] [PATCH 1/2] board/lemaker/bananapro: fix wlan module

Restore a patch which disables 00B IRQ for 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.
