[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. Signed-off-by: Stephen Neuendorffer <stephen.neuendorffer@xilinx.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

2582 Xilinx hwicap devices provide access to the configuration logic
2583 of the FPGA through the Internal Configuration Access Port
2584 (ICAP). The ICAP enables partial reconfiguration of the FPGA,
2585 readback of the configuration information, and some control over
2586 'warm boots' of the FPGA fabric.
