Add the Victor V86P Machine

This is a portable computer based around 80C86 processor and Chips &
Technologies chip set. It features a 640x200 monochromatic LCD display,
and up to two 720k 3.25" floppy drives.

It can optionally contain a hard drive controller along with 20M 3.25" MFM
hard drive in place of one floppy drives, which is not emulated yet.
Also not emulated is the expanded memory over 640K.

At least two versions of BIOS have been seen in the wild -- one from
89/09/04 another from 09/12/20.

The MD5 checksums of the ROM images (a pair of chips for each BIOS versions
and a character ROM) are as follows:

  SHA1(ce39ab220de25bbd824dbd5c7411c88f3a8d7430) =
  roms/machines/v86p/INTEL8086AWD_BIOS_S3.1_V86P_090489_Even.rom
