fsl,mpc5200-mscan nodes

-----------------------

In addition to the required compatible-, reg- and interrupt-properites, you can

also specify which clock shall be used for the bus:

also specify which clock source shall be used for the controller:



- fsl,mscan-clk-src	- a string describing the clock source. Valid values

			  are "ip" for IP_CLK and "sys" for SYS_XTAL.

			  "sys" is the default in case the property is not

- fsl,mscan-clock-source- a string describing the clock source. Valid values

			  are:	"ip" for ip bus clock

				"ref" for reference clock (XTAL)

			  "ref" is default in case this property is not

			  present.
