uml: remove __u64 usage from physical memory subsystem

Eliminate some uses of __u64 in the physical memory support.  It's hard to get
a definition of __u64 in both kernel and userspace code on x86_64, so this
changes them to unsigned long long.

There are also a copyright update and formatting comment removal from the
affected header.
