It's not operating on FD, and we've provided a nice reimplementation
that does. Let's use it instead.

The cited commit removed --get suboptions but failed to update the usage
and examples. Remove the duplicated examples from the comments in the
interest of if not single but at least fewer points of truth.
Fixes: 20d6e0f41b3b ("tools/intel_gpu_frequency: remove use of getsubopt")

We are, the build system takes care of that.

getsubopt is not available in android. The "get" option
doesn't really need sub-options, just display all the
current frequency settings (as per discussion with
Ben Widawsky)
Ben v2: Remove the -geff example in the header
Fixed another typo for the --set while there (found by Dave Gordon)

Add a parameter for the size of the act_upon array in the parse function
since its size cannot be calculated with ARRAY_SIZE from just the
pointer.

WARNING: very minimally tested
In general you should not need this tool. Its primary purpose is for
benchmarking, and for debugging performance issues.
For many kernel releases now sysfs has supported reading and writing the GPU
frequency. Therefore, this tool provides no new functionality. What it does
provide is an easy to package (for distros) tool that handles the most common
scenarios.
v2:
Get rid of -f from the usage message (Jordan)
Add space before [-s (Jordan)
Add a -c/--custom example (Jordan)
Add a setting for resetting to hardware default (Ken)
Replicate examples in commit message in the source code. (me)
v3:
Its not It's (me)
Add --help/-h to usage
Add Version + man page
Rename tool to intel_gpu_frequency, from intel_frequency
Remove "sudo" from the examples
