usb: typec: ucsi_ccg: Add OF support

Add device-tree support for the Cypress CCG UCSI driver. The device-tree
binding for the Cypress CCG device uses the standard device-tree
'firmware-name' string property to indicate the firmware build that is
used.

The NVIDIA GPU I2C driver has been updated to use an ACPI string
property that is also named 'firmware-build' and given that this was the
only users of the 'ccgx,firmware-build' property, we can now remove
support for this legacy property.
