ramips: fix sd polling
This is fixed in 18.06, it appears again in 19.07.
Currently mt7628 sdcard driver do not support polling mode which is for
the device do not have card-detect pin to detect sd card insert. Without
this patch, device will not detect sdcard is inserted. This patch is a
fix of that.
