optionrom: disallow int19 redirect for pnp roms.
Check whenever pnp roms attempt to redirect int19, and in case it does log a message and undo the redirect. A pnp rom should not need this, we have BEVs and BCVs for that. Nevertheless there are roms in the wild which are redirecting int19. At least some BIOS implementations for physical hardware have a config option in the setup to allow/disallow int19 redirections, so just not allowing this seems to be the way to deal with this situation.

Welcome to the SeaBIOS project! This project implements an X86 legacy
bios that is built with standard GNU tools.
Please see build and developer information at:
For the impatient, SeaBIOS is built for QEMU and tested on QEMU with:
qemu -bios out/bios.bin
SeaBIOS can be configured with kconfig. To change the default
configuration one can run "make menuconfig" prior to running "make".
For other types of builds, and for more detailed developer
documentation, please see the online documentation listed above.
