tools, testing, add test for intel_pstate driver 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 Cc: Shuah Khan <shuahkh@osg.samsung.com> Cc: linux-api@vger.kernel.org Signed-off-by: Prarit Bhargava <prarit@redhat.com> Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com>

selftests/intel_pstate: Update makefile to match new style 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.
