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. For ACPI a 16-bit property named 'ccgx,firmware-build' is used and
if this is not found fall back to the 'firmware-name' property.

You don't need this anymore. You already added the new property
"firmware-name" to drivers/i2c/busses/i2c-nvidia-gpu.c.


I was planning to get rid of this here, but I was not sure if AMD need this. I see now that Sanket has confirmed they don't use this and so will drop it from here.
