crypto: qat - enable power management debugfs for GEN6 devices

Browse Source 
The QAT driver includes infrastructure to report power management (PM)
information via debugfs. Extend this support to QAT GEN6 devices
by exposing PM debug data through the `pm_status` file.

This implementation reports the current PM state, power management
hardware control and status registers (CSR), and per-domain power
status specific to the QAT GEN6 architecture.

The debug functionality is implemented in adf_gen6_pm_dbgfs.c
and initialized as part of the enable_pm() function.
