usb: dwc3: Add support for usb-conn-gpio connectors

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 a regulator in your system provides VBUS
directly to the connector instead of supplying 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.

arm64: dts: qcom: qcs404-evb: Specify the VBUS input supply

The regulator-fixed property allows you to specify the input supply. Do so
now for completeness.

usb: dwc3: Add support for role-switch-default-mode binding

Support the new role-switch-default-mode binding for configuring
the default role the controller assumes as when the usb role is
USB_ROLE_NONE

misc: hisi_hikey_usb: Driver to support usb functionality of Hikey960

The HiKey960 has a fairly complex USB configuration due to it
needing to support a USB-C port for host/device mode and multiple
USB-A ports in host mode using a single USB controller.

See schematics here:
https://github.com/96boards/documentation/raw/master/consumer/hikey/hikey960/hardware-docs/HiKey960_Schematics.pdf

This driver acts as a usb-role-switch intermediary, intercepting
the role switch notifications from the tcpm code, and passing
them on to the dwc3 core.

In doing so, it also controls the onboard hub and power gpios in
order to properly route the data lines between the USB-C port
and the onboard hub to the USB-A ports.

NOTE: It was noted that controlling the TYPEC_VBUS_POWER_OFF and
TYPEC_VBUS_POWER_ON values here is not reccomended. I'm looking
for a way to remove that bit from the logic here, but wanted to
still get feedback on this approach.

integration-linux-qcomlt-qcs404-usb-v3-00: phy: qcom: usb-hs-snp-28nm: Remove regulator_set_voltage logic

phy: qcom: usb-hs-snp-28nm: Remove regulator_set_voltage logic

regulator_set_voltage() and the associated logic in
qcom_snps_hsphy_config_regulators() can be gotten rid of entirely.

This patch subtracts the logic around regulator_set_voltage(). A previous
commit set a floor on the regulator minimum voltage.

Setting regulator_set_load() in the init routine and
regulator_bulk_enable() in the PHY power on/off routine will accomplish the
same thing.
