Subject: i2c: nvidia-gpu: Add ACPI property to align with device-tree
From: Wayne Chang <waynec@xxxxxxxxxx>
commit f510b0a3565b9231e828e23a7e0f9790b97edf96 upstream.
Device-tree uses the 'firmware-name' string property to pass a name of
the firmware build to the Cypress CCGx driver. Add a new ACPI string
property to the NVIDIA GPU I2C driver to align with device-tree so that
we can migrate to using a common property name for both ACPI and
device-tree.
