imx: ddr: imx8m: Move selfref_en after DDR scrub

When doing DDR scrub, the DDR may enter into self refresh if the
selfref_en is enabled before DDR scrub. This will cause scrub
can't complete that SBRSTAT.scrub_done won't be set.

Since the selfref_en can be programmed during the course of
normal operation, move it after DDR scrub
