mxc: add common debug board for 3-stack platforms

The debug board is little different for all mxc 3-stack(PDK)
platforms, it is possible here to add a common implementation to
support this board.

+          The debug board is an integral part of the MXC 3-stack(PDK)
+          platforms, it can be attached or removed from the peripheral
+          board. On debug board, several debug devices(ethernet, UART,
+          buttons, LEDs and JTAG) are implemented. Between the MCU and
+          these devices, a CPLD is added as a bridge which performs
+          data/address de-multiplexing and decode, signal level shift,
+          interrupt control and various board functions.
