[PATCH] usb: typec: qcom-pmic: add CONFIG_OF dependency

[Randy Dunlap]

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]

Fixes: 7d9f1b72b296 ("usb: typec: qcom-pmic-typec: switch to DRM_AUX_HPD_BRIDGE")
