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.

2.43.0

Initial support for Dell XPS 9345 13" 2024 (Tributo) based on X1E80100.

Working:
* Touchpad
* Keyboard (only post suspend&resume, i2c-hid patch required [1])
* Touchscreen
* eDP (low-res IPS, OLED) with brightness control
* NVME
* USB Type-C ports in USB2/USB3 (one orientation)
* WiFi
* GPU/aDSP/cDSP firmware loading (requires binaries from Windows)
* Lid switch
* Sleep/suspend, nothing visibly broken on resume

Not working:
* Speakers (WIP, pin guessing, x4 WSA8845)
* Microphones (WIP, pin guessing)
* Fingerprint Reader (WIP, USB MP with ptn3222)
* USB as DP/USB3 (WIP, PS8830 based)
* Camera

Should be working, but cannot be tested due to lack of hw:
* higher res IPS panel
