mb/asus/p5qpl-am: Add p5g41t-m_lx as a variant

This board has more or less the same as the p5qpl-am except for DDR3
memory and different colors on the ports. Tested with Arch Linux with
kernel 4.20.0-arch1-1-ARCH.

What is tested and works:
 - 800/1066/1333 MHz CPUs and DDR3 sticks at 800/1066 MHz
     Some bugs are still present in the DDR3 raminit code though.
 - Ethernet
 - Internal programmer with both coreboot and stock firmware.
 - PCI and PCIe x1 slots
 - All USB ports
 - S3 resume
 - SATA ports
 - PEG
 - Rear audio output
