[PATCH] arm64: dts: qcom: talos-lyra-evk: Add CYPD6129 Type-C support

[Akash Kumar]

Add support for the Cypress CYPD6129 dual Type-C PD controller on the
Talos Lyra EVK.

Enable the controller on I2C5 at address 0x40, configure its GPIO86
interrupt and wakeup support, and describe both USB Type-C connectors.
Connect the connectors to USB1 and USB2 through USB role-switch
remote-endpoint links.

Configure both USB controllers in OTG mode with usb-role-switch support
so that the CYPD6129 controller can manage their USB data roles.

USB1 is routed to the daughter-card board-to-board connector. Add a
fixed USB1 VBUS regulator controlled by PM8150 GPIO10 to provide and
control VBUS for the USB port on the daughter card. Configure the
corresponding PM8150 GPIO pinctrl state and keep the regulator enabled
for the board configuration.

Add the TLMM GPIO64 VBUS boost enable as a GPIO hog. This enables the
5 V boost converter required to generate the VBUS supply for the USB
daughter-card connector. The boost converter output is set to 5 V by
the feedback network consisting of R2403 and R2401:

    VOUT = 0.6 * (1 + R2403 / R2401)
         = 0.6 * (1 + 75K / 10K)
         = 5 V

The changes also add the I2C5 alias, CYPD6129 pinctrl configuration,
wakeup-source properties, USB endpoint connections, and the required
VBUS power-control GPIO descriptions.
