mb/asus/p5qpl-am: Add mainboard

This mainboard has the BSEL straps hooked up to the SuperIO
similar to the ASUS P5GC-MX and might therefore require a restart.

Tested:
- FSB 800, 1067 and 1333MHz CPUs
- USB
- Ethernet
- Serial
- 2 DIMM slots
- SATA
- Libgfxinit (VGA)

TESTED with SeaBIOS (sercon disabled) and Linux 4.19.
