Support a common method to probe all devices associated with uclass.
This includes data structures and code for finding the first device and looping for remaining devices associated with uclasses (groups of devices with the same purpose, e.g. all SERIAL ports will be in the same uclass).
An example is SBSA compliant PL011 UART IP, where firmware does the serial port initialization and prepare uart device to let the kernel use it for sending and reveiving the characters.SERIAL uclass will use this function to initialize PL011 UART ports.
The feature is enabled with CONFIG_DM.
