Subject: [RFC][PATCH] arm64: Switch to %px for printing some addresses at bootup

With the move to stricter %p printing, several of the addresses
are no longer printed out. Switch to %px so they always get printed.

I'll admit to finding the new %p restrictions particularly irritating
here because I like seeing the print out of the virtual addresses for
debugging and checking. It might also be worth discussing whether we
should be printing anything out?
