This adds support for the Librem 11 tablet, using the ME 13.50.15.1436
binary from the original BIOS (version 28.D8.E1.021) and FSP binaries
from a Jasper Lake Chromebook.
The following features were tested with PureOS:
* Audio (speakers, microphone, headset jack)
* Cameras
* Display
* Touchscreen and pen
* Keyboard cover, with tablet/laptop mode switch indicated via ACPI
* Power and volume buttons
* USB-C ports (USB 2/3, DP alt mode, PD charging)
* SD card reader
* WLAN
* Bluetooth
* NVMe SSD (socketed)
* Battery state information from EC
* Accelerometer
A UART is accessible with soldering via test points on the mainboard,
documented in the mainboard Kconfig with a toggle to enable it for
coreboot logging.
