parisc: Fix serio address output

[ Upstream commit 785145171d17af2554128becd6a7c8f89e101141 ]

We want the hpa addresses printed in the serio modules, not some
virtual ioremap()ed address, e.g.:

 serio: gsc-ps2-keyboard port at 0xf0108000 irq 22 @ 2:0:11
 serio: gsc-ps2-mouse port at 0xf0108100 irq 22 @ 2:0:12
