arm64: dts: qcom: x1-crd: 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 (func1/edp0_hot and
bias-disable according to the ACPI DSDT), which is defined as
&edp0_hpd_default template in x1e80100.dtsi.
