[SRU][Vivid][PATCH] ACPI / PCC: Use pr_debug() for debug messages in pcc_init()

[Colin King]

From: "Rafael J. Wysocki" <rafael.j.wysocki at intel.com>

BugLink: https://bugs.launchpad.net/bugs/1524930

pcc_init() uses pr_err() to print two messages that are really debug
and not interesting to users.  Replace those pr_err() with pr_debug().
