* Pin configuration nodes

Required properties:
- pio-map : array of pin configurations.  Each pin is defined by 6
  integers.  The six numbers are respectively: port, pin, dir,
  open_drain, assignment, has_irq.
  - port : port number of the pin; 0-6 represent port A-G in UM.
  - pin : pin number in the port.
  - dir : direction of the pin, should encode as follows:

     0 = The pin is disabled
     1 = The pin is an output
     2 = The pin is an input
     3 = The pin is I/O

  - open_drain : indicates the pin is normal or wired-OR:

     0 = The pin is actively driven as an output
     1 = The pin is an open-drain driver. As an output, the pin is
         driven active-low, otherwise it is three-stated.

  - assignment : function number of the pin according to the Pin Assignment
    tables in User Manual.  Each pin can have up to 4 possible functions in
    QE and two options for CPM.
  - has_irq : indicates if the pin is used as source of external
    interrupts.

Example:
     ucc_pin@01 {
	pio-map = <
	/* port  pin  dir  open_drain  assignment  has_irq */
