mips: r4000: Renovate coding style
The script checkpatch.pl located in scripts folder was used to detect all errors and warrnings in file: hw/mips/mips_r4k.c This mips r4000 machine file was edited and all the errors and warrings generated by the checkpatch.pl script were corrected and then the script was ran again to make sure there are no more errors and warnings.
