Title:
[X1E] Support HP EliteBook Ultra G1q 14

Status in ubuntu-concept:
Confirmed
Status in linux package in Ubuntu:
In Progress

Bug description:
Add support for the Snapdragon X Elite powered HP EliteBook Ultra G1q
14

=== Device Information ===
Manufacturer: HP
Product Name: HP EliteBook Ultra G1q 14 inch Notebook AI PC
Version: ConfigID
Wake-up Type: Power Switch
SKU Number: A37B0ET#UUW
Family: 103C_5336AN HP EliteBook Ultra

=== Notes ===

No keyboard in GRUB on USB boot.
Boot loop using default ISO.
Added the following to grub using livefs-edit and I am able to boot and install. Using devicetree from OmniBook seems to work well enough to get started.

regexp "HP EliteBook Ultra G1q 14.*" "$system_product_name"
if [ $? == 0 ]; then
        cmdline="clk_ignore_unused pd_ignore_unused cma=128M "
        dtb="devicetree /casper/dtbs/x1e80100-hp-omnibook-x14.dtb"
fi

After running qcom-firmware-extract I have a working system with -it
seems- pretty much the same issues as OmniBook.

Keyboard is OK in installed GRUB.

=== What does not work ===
Internal speakers
Internal webcam
Bluetooth detects and pairs but unable to connect (will troubleshot this some more with other devices).
Function keys
Brightness full on around 95% (in gnome), if I go above it it "starts over"

Not sure about suspend yet, will leave it suspended and check battery
drain tomorrow

I am happy to provide more details.
