Recent changes from Bamvor (88baa78d1f318) have standardized the
variable names like TEST_GEN_FILES and removed the need for make targets
all and clean.
These changes bring the intel_pstate test inline with those changes.

The build was showing the warning:
aperf.c:60:27: warning: iteration 2147483647 invokes undefined behavior
[-Waggressive-loop-optimizations]
for (i=0; i<0x8fffffff; i++) {
This change sets i, cpu and fd to unsigned int as they should not need
to be signed.

This test used the cpupower utility to set the cpu frequency from the
maximum turbo value to the minimum supported value in steps of 100 MHz.
The results are displayed in a table which indicate the "Target" state,
or the requested frequency in MHz, the Actual frequency, as read from
/proc/cpuinfo, the difference between the Target and Actual frequencies,
and the value of MSR 0x199 (MSR_IA32_PERF_CTL) which indicates what
pstate the cpu is in, and the value of
/sys/devices/system/cpu/intel_pstate/max_perf_pct X maximum turbo state
