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

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.
