qdbusb.sys failed in Win11 26H1 HLK test
The registry keys of qcwdfser.inf encountered errors in Win11 26H1 HLK test. In 26H1 HLK, customer highlighted that test item "DF InfVerify INF Verification" on Win11 26H1 HLK test and encountered errors on qcwdfser.inf

RCA: qdbusb.sys uses absolute registry path for setting up friendly name
qcwdfser.inf didn't had parameter subkey for QCDriverPowerManagementEnabled and QCDriverSelectiveSuspendIdleTime which is required for 26H1 HLK . Also QCDriverPowerManagementEnabled is not needed as it is not used anywhere

Solution: Added changes for adding parameters in inf and in driver. Modified function for fetching path and setting friendly name in qdbusb mdoule
