parport_pc: add base_hi BAR for oxsemi_840

Use the 2nd BAR for the oxsemi_840 chip as BAR for base_hi.  Tested with:

Parallel controller [0701]: Oxford Semiconductor Ltd VScom 011H-EP1
        1 port parallel adaptor [1415:8403] (prog-if 03 [IEEE1284])

This patch is needed to make 'TRISTATE' work with that adaptor.
