Add the IBM PC 330/350 type 65x6. (#6315)
* Change BIOS loading (temporarily) * Change GPIO related stuff on the PC 330 65x6... CPU clock is now properly reported up to 166 MHz. * Add IBM PC 330 type 65x6 machine table entry. * Add IBM PC 330 type 65x6 machine definition. * Fix a compile breaking error. * Block AMD K5/Cx686 CPUs from the IBM PC 330/350 type 65x6. * Correct the PC 330/350 ROM path.
