microblaze: Fix early cmdline for CMDLINE_FORCE
This patch fixed parsing early parameters because current implementation does that early parse DTS command line and then parse CMDLINE line which is compiled-in. For case that DTS doesn't contain command line is copied command line from kernel with is done in prom.c that's why I can remove it from machine_early_init.
