Add VBUS regulator GPIO information, so that USB OTG port can
also be used in host mode.

Add PHY voltage supply information fixing the following kernel message:
2188000.ethernet supply phy not found, using dummy regulator
Also add PHY clock information to avoid depending on the bootloader
programming correct values.
The bootloader also sets some reserved registers in the PHY as
advised by Qualcomm, which is not supported by the bindings/kernel
driver, so the reset GPIO has not been added intentionally.

Explicitly mark I2C GPIOs as open drain to fix the following
kernel message being printed:
enforced open drain please flag it properly in DT/ACPI DSDT/board file
