[romprefix] Report a pessimistic runtime size estimate
PCI3.0 allows us to report a "runtime size" which can be smaller than
the actual ROM size. On systems that support PMM our runtime size
will be small (~2.5kB), which helps to conserve the limited option ROM
space. However, there is no guarantee that the PMM allocation will
succeed, and so we need to report the worst-case runtime size in the
PCI header.
Move the "shrunk ROM size" field from the PCI header to a new "iPXE
ROM header", allowing it to be accessed by ROM-manipulation utilities
such as disrom.pl.
