dt/flattree: explicitly pass command line pointer to early_init_dt_scan_chosen
This patch drops the reference to a global 'cmd_line' variable from early_init_dt_scan_chosen, and instead passes the pointer to the command line string via the *data argument. Each architecture does something slightly different with the initial command line, so it makes sense for the architecture to be able to specify the variable name.
