It seems like what we need is to pull out the command line processing
code from early_init_dt_scan_nodes and put that into a new function,
say early_init_setup_cmdline, then have both early_init_dt_scan_nodes
and powerpc's early_init_devtree call early_init_setup_cmdline.

I'll split this series into two, one for the PS3 updates, and one
that adds early_init_setup_cmdline.
