[ Upstream commit 8810e055b57543f3465cf3c15ba4980f9f14a84e ]
Modify the code so it can be compiled tested in configurations that do not have ACPI enabled.
It fixes the following errors: drivers/media/pci/intel/ipu-bridge.c:103:30: error: implicit declaration of function ‘acpi_device_handle’; did you mean ‘acpi_fwnode_handle’?
