Introduce support for the mentioned laptop. Very similar to other X1E laptops, device tree was derived by analyzing dtsi of existing models and ACPI tables of this laptop [1]. Most notable difference were * TZ protected SPI19. * Keyboard only working after suspend/resume sequence, will do a follow up patch to i2c-hid. * Lots of small deviations in LDOs voltages. Successfully tested with Debian 12 and Gnome, although this required additional patches, namely harcode GPU chipid, apply [2] and _revert_ [3] - same as in Abel Vesa's branches. Without last two the boot process is terminated by TZ. Firmware for GPU/aDSP/cDSP was extracted from Windows, WiFi firmware from upstream linux-firmware. Quite a few things alraedy work, details in patches, quite a few still in WIP or TODOs. Since fixing these may take me a while due to lack of documentation, sending current progress as its very much usable.
