Device Tree additions for LPC18xx platform
 - CREG clock controller
 - Real Time Clock (RTC)
 - Analog peripherals (ADC/DAC)
 - Warning fixes for the new dtc compiler

With the CREG clock controller in place it is now possible
to enable the internal RTC on LPC18xx/43xx platforms. The
analog peripherals (ADC/DAC) has also been added here and
enabled on both the EA4357 dev kit and Hitex eval board.

In addition to the new entries there are a fixes for the
DT warnings generated by the new dtc.
