wifi: mt76: mt7915: fallback to non-wed mode if platform_get_resource fails in mt7915_mmio_wed_init()
[ Upstream commit 5f9d5d4fc561e7bd3a18742f1fdb96cab98f1870 ]
mt76 assumes mt7915_mmio_wed_init can fail just after wed driver has
been attached running mtk_wed_device_attach().
Fall back to non-wed mode if platform_get_resource fails in
mt7915_mmio_wed_init routines.
