* rk_display_init() - Try to enable the given display device
*
* This function performs many steps:
* - Finds the display device being referenced by @ep_node
* - Puts the VOP's ID into its uclass platform data
* - Probes the device to set it up
* - Reads the EDID timing information
* - Sets up the VOP clocks, etc. for the selected pixel clock and display mode
* - Enables the display (the display device handles this and will do different
* things depending on the display type)
* - Tells the uclass about the display resolution so that the console will
* appear correctly
*
* @dev: VOP device that we want to connect to the display
* @fbbase: Frame buffer address
* @l2bpp Log2 of bits-per-pixels for the display
* @ep_node: Device tree node to process - this is the offset of an endpoint
* node within the VOP's 'port' list.
* @return 0 if OK, -ve if something went wrong
