mb/lenovo/w541: Add ThinkPad W541

Add support for the ThinkPad W541 based on Peter Lemenkov's initial W541
port. Compiled and tested with SeaBIOS and Tianocore booting into Arch
Linux 5.10.32-lts. The Haswell mrc.bin blob is required.

Tested working:
- SATA SSD
- SATA DVD drive
- M.2 SATA
- All USB ports
- SD card reader
- Speakers/headphone jack
- Keyboard/touchpad
- libgfxinit
- VGA
- mini DisplayPort (Thunderbolt untested)
- eDP laptop screen
- NVIDIA GPU in Linux
- Camera/Mic
- Smartcard reader
- Internal flashing when IFD is unlocked
- ThinkPad basic dock (VGA, USB, Ethernet)
- CMOS options
- WLAN
- Bluetooth
- Ethernet
- Using me_cleaner
- All DDR3 slots

Not working:
- Keyboard backlight
- First boot can take up to 20s (MRC.bin is slow)

Untested:
- Thunderbolt
- Internal flashing when IFD is locked
- Other ThinkPad docks (DisplayPort, DVI, Audio)
- ExpressCard slot
- Battery thresholds
- WWAN card
- Fingerprint reader
- USB Debug console
