The clock frequency property of the device tree node fsl,mpic is
added as it is needed by the PCI driver to function in newer
Linux version.

Pull the board device reset GPIO pin high as this prevents
PCI bus probing.
The function da923rc_board_init_r is called at the postcore
initcall level so that the udelay function can take advantage
of the core initialisation.
