X1/X1 Plus variant of the said device comes in either FHD+ OLED or FHD+
LCD panel, and shares the same model number UX3407QA. It appears LCD
panel's brightness adjustment is PWM backlight controlled, so a
dedicated device-tree is required. Introduce dedicated compatibles with
fallback to 'asus,zenbook-a14-ux3407qa' as they are otherwise the same.

The laptop comes in two variants:
* UX3407RA, higher end, FHD+ OLED or WOXGA+ OLED panels
* UX3407QA, lower end, FHD+ OLED or FHD+ LCD panels
Even though all three panels work with "edp-panel", unfortunately the
brightness adjustmenet of LCD panel is PWM based, requiring a dedicated
device-tree. Convert "x1p42100-asus-zenbook-a14.dts" into ".dtsi" to
allow for this split, introduce new LCD variant. Leave current variant
without postfix and with the unchanged model name, as some distros
(eg. Ubuntu) rely on this for automatic device-tree detection during
kernel installation/upgrade.
As dedicated device-tree is required, update compatibles of OLED
variants to correct ones. Keep "edp-panel" as fallback, since it is
enough to make the panels work.
While at it moving .dts, .dtsi around, drop 'model' from the top level
x1-asus-zenbook-a14.dtsi as well.

Unlike UX3407QA with ath11k, UX3407RA comes with ath12k. Definitions
were not added during initial bringup due to lack of hardware to test
it. Add missing definitions that were now confirmed to work.
