pass: pmqos: Group the private data of PMQoS module into struct pmqos

PASS uses the 'scenario' expression which indicates the unique user-scnaerio
or the specific situation. 'struct pass_pmqos' is used to handle 'scenario'.

'struct pass_pmqos' is used on multiple modules and then it might have
both common variables and specific variables used on particular PASS module.

So, group the private data of PMQOS module into the 'struct pmqos'.
