env/vtophys: combine DPDK physical address lookups

Browse Source 
vtophys_get_paddr() and vtophys_get_dpdk_paddr() are doing similar
things; combine them into one function that works for all DPDK
memory addresses.

Part of the vtophys test is temporarily disabled until the next commit,
which will register all DPDK memory at startup and stop lookiing up
addresses at runtime.
