[][openwrt][common][emmc][Change and load loop kernel module at early stage during kernel startup]

[Description]
Change and load loop kernel module at early stage during kernel startup.
That is to say, in /etc/modules-boot.d, we'll have 30-loop symlink.

Without this patch, we can't create loop device with eMMC/SD on mt7988.

[Release-log]
