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.
