FDT: only call boot_get_fdt from generic code

All arches except nios2 and microblaze call boot_get_fdt
from bootm_start in common/cmd_bootm.c.

Having nios2 and microblaze do so as well removes code from
their respective do_bootm_linux routines and allows removal of
a nasty ifdef from bootm_start.

In the case where boot_get_fdt returns an error bootm_start
returns and the platform specific do_bootm_linux routines
will never get called.

Also only check argv[3] for an fdt addr if argc > 3 first.
This is already the case for nios2.
