    can: pch_can: fix sparse warning
    
    This patch fixes the following sparse warning:
    
    drivers/net/can/pch_can.c:231:26: warning: incorrect type in argument 1 (different address spaces)
    drivers/net/can/pch_can.c:231:26:    expected unsigned int [usertype] *addr
    drivers/net/can/pch_can.c:231:26:    got unsigned int [noderef] <asn:2>*<noident>
    
    Let pch_can_bit_{set,clear} first parameter be a void __iomem pointer.
