It contains registers such as I2C speed mode that need to be accessible by other nodes. Remove fixed-clocks previously used; replace references. Add parent crystal clock, fixed at 30MHz. Add pin nodes for all functions. Add mobileye,eyeq5-olb compatible node, hosting clk, reset and pinctrl. Add reset and pinctrl references to UART nodes.
