cpufreq: amd-pstate: change amd-pstate driver to be built-in type
[ Upstream commit456ca88d8a
] Currently when the amd-pstate and acpi_cpufreq are both built into kernel as module driver, amd-pstate will not be loaded by default in this case. Change amd-pstate driver as built-in type, it will resolve the loading sequence problem to allow user to make amd-pstate driver as the default cpufreq scaling driver.
