mb/asus/p5ql-em: Add mainboard

Tested, working:
- First dimm slot of each channel
- USB, SATA
- CPU FSB at 800, 1067 and 1333MHz
- Libgfxinit on DVI and VGA slot
- PCI slot
- Realtek NIC (configure MAC address in Kconfig)
- PEG slot
- PS2 keyboard

Tested, not working:
- second dimm slot for each channel. Those are hooked up to the second
  rank of the channel, instead of rank 3 and 4. The raminit does not
  support such setups.

Untested:
- PCIe x1 slot, likely works fine
- HDMI

Tested using SeaBIOS 1.12, Linux 4.19.
