Commit a7d550f82b445cf218b47a2c1a9c56e97ecb8c7a (of: fdt: Honor CONFIG_CMDLINE*
even without /chosen node) moved the processing of the kernel built-in command
line (CONFIG_CMDLINE) from the early_init_dt_scan_chosen routine to the
early_init_dt_scan_nodes routine.
The current powerpc startup code does not call into early_init_dt_scan_nodes, so
processing of CONFIG_CMDLINE never happens, even if CONFIG_CMDLINE_FORCE=y.
The result is an empty kernel command line, and mounting of the root file system
then fails with a kernel panic (not syncing: VFS: Unable to mount root fs).
Let's revert the above commit and redo the missing /chosen node handling
within early_init_dt_scan_chosen().
