tests/pm_rc6_residency: fix check if RC6P or RC6PP is enabled

Browse Source 
The test checks the residency in a given RC6 state or any deeper states
that are also enabled. For example the RC6 subtest checks the combined
residency in RC6/RC6P/RC6PP. Since the kernel reported value for the RC6
residency doesn't include the RC6P or RC6PP residency we need to adjust
the RC6 value accordingly. A similar adjustment is needed for the RC6P
subtest.
