Subject: [PATCH 0/9] arm64: dts: qcom: x1: Add missing pinctrl for eDP HPD

At the moment, we indirectly rely on the boot firmware to set up the
pinctrl for the eDP HPD line coming from the internal display. If the boot
firmware does not configure the display (e.g. because a different display
is selected for output in the UEFI settings), then the display fails to
come up and there are several errors in the kernel log:

 [drm:dpu_encoder_phys_vid_wait_for_commit_done:544] [dpu error]vblank timeout: 80020041
 [drm:dpu_kms_wait_for_commit_done:524] [dpu error]wait for commit done returned -110
 [drm:dpu_encoder_frame_done_timeout:2715] [dpu error]enc40 frame done timeout
 ...

Fix this by adding the missing pinctrl for gpio119 for all the boards
supported upstream.

I ran into this issue on the X1E CRD while testing some things and had this
fix in my local tree for a while. Chris made a similar patch for the T14s
[1], this series fixes up all of the boards upstream.
