Subject: [PATCH] intel_pstate: Turn per cpu printk into pr_debug

From: Andi Kleen <ak@...ux.intel.com>

On larger systems intel_pstate currently spams the boot up
log with its "Intel pstate controlling ..." message for each CPU.
It's the only subsystem that prints a message for each
CPU.

Turn the message into a pr_debug.
