sh: Tidy up the sh bios VBR handling.
This moves the VBR handling out of the main trap handling code and in to the sh-bios helper code. A couple of accessors are added in order to permit other kernel code to get at the VBR value for state save/restore paths. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
