intel_pstate: Add get_scaling cpu_defaults param to Knights Landing
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.
Fixes: b34ef932d79a (intel_pstate: Knights Landing support)
