arm64: dts: ti: iot2050: Add overlays for M.2 used by firmware

Browse Source 
To allow firmware to pick up all DTs from here, move the overlays that
are normally applied during DT fixup to the kernel source as well. Hook
then into the build nevertheless to ensure that regular checks are
performed.
