When run dpdk-l3fwd with '-u' on non-X86 platform, user would happen a noisy print as the following: "POWER: Uncore frequency management not supported/enabled on this kernel. Please enable CONFIG_INTEL_UNCORE_FREQ_CONTROL if on Intel x86 with linux kernel >= 5.6".
The root cause is that intel_uncore driver's .init() will be called on any platform when use automatic detection mode. The function in intel_uncore driver will print above log on non-X86 platform. But the existing uncore core cannot solve this problem unless break ABI to add new callback. So reduce its log level to avoid this incorrect prompt.
