MIPS: ingenic: Use common cmdline handling code

Browse Source 
jz4740_init_cmdline appends all arguments from argv (in fw_arg1) to
arcs_cmdline, up to argc (in fw_arg0). The common code in
fw_init_cmdline will do the exact same thing when run on a system where
fw_arg0 isn't a pointer to kseg0 (it'll also set _fw_envp but we don't
use it). Remove the custom implementation & use the generic code.
