Subject: Bluetooth: hci_sync: Convert MGMT_OP_SET_PHY_CONFIGURATION
Patch-mainline: v5.17-rc1
Git-commit: 71efbb08b538d925733e0e07d4f48d996292ac5e
References: jsc#PED-1407

mgmt-test paths:
Set PHY 2m Success
Set PHY coded Succcess
Set PHY 1m 2m coded Succcess
Set PHY 2m tx success
Set PHY 2m rx success
Set PHY Invalid Param
Start Discovery - (2m, Scan Param)
Start Discovery - (coded, Scan Param)
Start Discovery - (1m, 2m, coded, Scan Param)
