Subject: intel_pstate: Add get_scaling cpu_defaults param to Knights Landing

From: Lukasz Anaczkowski <lukasz.anaczkowski@intel.com>

commit 69cefc273f942bd7bb347a02e8b5b738d5f6e6f3 upstream.

Scaling for Knights Landing is same as the default scaling (100000).
When Knigts Landing support was added to the pstate driver, this
parameter was omitted resulting in a kernel panic during boot.
