firmware: xilinx: Add debugfs interface
Firmware-debug provides debugfs interface to all APIs.
Debugfs can be used to call firmware APIs with required
parameters.
Usage:
* Calling firmware API through debugfs:
# echo "<api-name> <arg1> .. <argn>" > /sys/.../zynqmp-firmware/pm
* Read output of last called firmware API:
# cat /sys/.../zynqmp-firmware/pm
Refer ug1200 for more information on these APIs:
* https://www.xilinx.com/support/documentation/user_guides/ug1200-eemi-api.pdf
Add basic debugfs file to get API version.
