nb/intel/snb: Abolish mainboard_should_reset_usb()

Of the 13 mainboards that implement mainboard_should_reset_usb() hook,
all but one do the same: Stop MRC from resetting USB when resuming
from S3 suspend.

This hook turns out is only here to facilitate a USB reset workaround
on samsung/stumpy for an old ChromeOS kernel which is no longer needed.

Drop the workaround, the hook, and headers no longer used.

roda/rv11/early_init.c is left with no useful code after this patch,
so drop it entirely from both bootblock and romstage.
