[POWERPC] Xilinx: hwicap: update booting-without-of.txt 



The ICAP device in Xilinx FPGAs differs slightly between different
FPGAs.  The driver needs an additional attribute in the device tree to
distinguish this.

      v) Xilinx hwicap



		Xilinx hwicap devices provide access to the configuration logic

		of the FPGA through the Internal Configuration Access Port

		(ICAP).  The ICAP enables partial reconfiguration of the FPGA,

		readback of the configuration information, and some control over

		'warm boots' of the FPGA fabric.



		Required properties:

		- xlnx,family : The family of the FPGA, necessary since the

                      capabilities of the underlying ICAP hardware

                      differ between different families.  May be

                      'virtex2p', 'virtex4', or 'virtex5'.
