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 Change-Id: I92cd15a245c4f1d8f57b304c9c3a37ba29c35431 Signed-off-by: Angel Pons <th3fanbus@gmail.com> Reviewed-on: https://review.coreboot.org/c/27089 Reviewed-by: Kyösti Mälkki <kyosti.malkki@gmail.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
