[pxe] Initialize EDX on PXE NBP entry and INT 1Ah
The PXE 1.x spec specifies that on NBP entry or on return from INT
1Ah AX=5650h, EDX shall point to the physical address of the PXENV+
structure. The PXE 2.x spec drops this requirement, simply stating
that EDX is clobbered. Given the principle "be conservative in what
you send, liberal in what you accept", however, we should implement
this anyway.
