Subject: [PATCH v1 0/3] X1E Dell XPS 9345 support

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.
