[PATCH 3/4] ARM: OMAP2: clean up string copying and formatting in omap3_cpuinfo

[Thorsten Blum <thorsten.blum@linux.dev>]

Replace scnprintf("%s") with the faster and more direct strscpy().

Remove unnecessary and inconsistent 'n' arithmetic when 'n = 0', and
when 'n' is no longer used at the end of the function.
