This patch makes the printout of the error message for failing to get a
VBUS regulator handle conditional on the error code being something other
than -EPROBE_DEFER.

Deferral is a normal thing, we don't need an error message for this.

This patch makes a gpio-usb-b-connector compatible child-node of usb3_dwc3.
Once enabled the gpio-usb-conn driver will handle USB ID and VBUS toggle.
Depending on the state detected by USB ID USB role switch notifications
will be propagated into the snps,dwc3 driver and the state toggled between
host or peripheral as appropriate.

In order to add a connector to the snps,dwc3 entires in the qcs404-evb.dtsi
we need to have a label for each snps,dwc3 entry so that later on we can
reference those entries like &usb3_dwc3{} or &usb2_dwc3{}.

This patch adds a label to each of the host controllers.

This patch adds the ability to probe and enumerate a connector based on
usb-conn-gpio. A device node label gpio_usb_connector is used to identify
a usb-conn-gpio as a child of the USB interface.

You would use usb-conn-gpio when the PMIC in your system provides VBUS
directly to the connector instead of routing via the USB PHY.

The parent device must have the "usb-role-switch" property, so that when
the usb-conn-gpio driver calls usb_role_switch_set_role() the notification
in dwc3 will run and the block registers will be updated to match the state
detected at the connector.

When using the usb-conn-gpio driver we need to bind into usb-role-switch in
the dwc3 driver so that the role switch detected at the port gets
propagated back into the qcom specific dwc3 logic.

extcon doesn't support vbus control; instead the usb-conn-gpio and usb role
switch notification should be used to inform the USB subsystem, DWC3
controller and QCOM DWC3 logic of the mode-switch.

This patch converts from using extcon to usb-conn-gpio for the type-c port.

The QCS404 SuperSpeed PHY does not supply or control VBUS directly. Instead
an external voltage regulator must be toggled to energize or de-energize
VBUS.

VBUS control logic should instead be handled by:

- usb-conn-gpio
- usb role switch notification

Remove VBUS control now.
