pit: Replace the tps65090 functions and adjust the hotplug detect line.

The functions which manipulated the tps65090 were removed a while ago because
    it isn't accessible directly from the AP, it's on an I2C bus that has to be
    accessed by the EC on our behalf. Now that that capability has been added, we
    can rewrite the small portion of the the tps65090 we actually used but using
    the EC passthrough commands.

Also, we should not be configuring the hardware display port hotplug detect
    line since we're using it as a GPIO for other purposes. The GPIO we're using
    instead defaults to being an input, but to be safe we should probably
    explicitly configure it as one anyway.
