[flashrom] [PATCH] Don't compile internal code if not selected

[Carl-Daniel Hailfinger]

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.
