The way of printing the pointer address for the 'port_base'
address got into compile warnings on some architectures
[-Wpointer-to-int-cast]. Instead of use '%08x' and cast
to an 'unsigned int' just make use of '%px' and avoid the
cast.

Fixes: d87da32372a0 ("phy: ralink: Add PHY driver for MT7621 PCIe PHY")

This whole message should be dropped as drivers should be quiet if all
is going well, and only print messages when things go wrong.

And why cc: linux-staging?

thanks,

Got it. Will move this into dev_dbg instead. Thanks.

True, sorry for that. Ctrl + r search for previous git send-mail and I
forgot to drop staging from there.
