usb: typec: qcom-pmic: add CONFIG_OF dependency

  DRM_AUX_BRIDGE depends on CONFIG_OF, so that is also needed here
to fix a kconfig warning:

WARNING: unmet direct dependencies detected for DRM_AUX_HPD_BRIDGE
  Depends on [n]: HAS_IOMEM [=y] && DRM_BRIDGE [=y] && OF [=n]
  Selected by [y]:
  - TYPEC_QCOM_PMIC [=y] && USB_SUPPORT [=y] && TYPEC [=y] && TYPEC_TCPM [=y] && (ARCH_QCOM || COMPILE_TEST [=y]) && (DRM [=y] || DRM [=y]=n) && DRM_BRIDGE [=y]

All but impossible for me to determine if this patch or
https://lore.kernel.org/all/20231205-drm_aux_bridge-fixes-v1-2-d242a0ae9df4@kernel.org/
is more appropriate.

I guess that Bryan is the person to ask about that.

I don't see anything wrong with Nathan's patch. It should clear up the kconfig warning,
so as long as it builds cleanly, it seems OK.

So, I see both versions of this fix

Nathan's
drivers/gpu/drm/renesas/rcar-du/Kconfig

Yours
drivers/gpu/drm/tve200/Kconfig

and virtually equivalent commit text. I think we agree its 1:1

So, maybe stick with Nathan's since he posted first.

Sure, I'm OK with that.
