Power up and GPIO functions have been moved to the driver MHL HPD event also triggers the HDMI HPD event since 8x30 FLUID device doesn't connect HPD line from 8334 to HPD line from MSM HDMI. The pull-up resistance in 8334 has been set to the recommended value so that the interrupts are sent over to MSM-USB driver.
