	A system's firmware description is recorded differently in sysfs depending if the system uses DT or ACPI. Add a helper to abstract this, allowing users not to care which of the two are used. For DT-based systems, the path is the full name of the DT node that represents the device. For ACPI-based systems, the path is the absolute namespace path to the ACPI object that represents the device. In both cases, the path is guaranteed to be unique and persistent as long as the system firmware is not modified.

2020-08-05	libcamera: sysfs: Add helper to lookup sysfs path of a character device	Niklas Söderlund
	Add a helper function to lookup the sysfs path of a character device. Store the function in a new libcamera::sysfs namespace as there is not class to host it.
