[PATCH 1/5] mips: jazz: Renovate coding style

[Filip Bozuta]

The script checkpatch.pl located in scripts folder was
used to detect all errors and warrnings in files:
    hw/mips/mips_jazz.c
    hw/display/jazz_led.c
    hw/dma/rc4030.c

All these mips jazz machine files were 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.
