Internal.c was always compiled in because it hosted the function internal_delay()

Move that function to udelay.c and compile internal.c only if really needed.
physmap.c is only needed if the programmer is internal or a PCI card.
Make its compilation conditional.

Corresponding to flashrom svn r822.
