description:
Abstraction fix; don't pull in physical segment/page definitions
in UVM external API, uvm_extern.h.  Because most users care only
virtual memory.

Device drivers use bus_dma(9) to manage physical memory.  Device
drivers pull in bus_dma(9) API, bus_dma.h.  bus_dma(9) implementations
pull in UVM internal API, uvm.h.

Tested By:      Compiling i386 ALL kernel
