m68k: code reformatting for all start.S files
This patch is style-related only, to reformat all the start.S code, actually not following a coherent style inside single files and between different cpu start.S files. Linux format has been respected, as - max line width at 80 columns - one 8 cols tab between asm instructions and operands - inline comments, where any, fixed at col 41 Signed-off-by: Angelo Dureghello <angelo@sysam.it>
