For now PSR2 is still disabled by default for all platforms but is
our intention to let debugfs to enable it for debug and tests
proporses, so intel_psr2_enabled() that is also used by debugfs to
decide if PSR2 is going to be enabled needs to take in consideration
the debug field.
v2: Using the switch/case that intel_psr2_enabled() already had to
handle this(DK)
