scsi: mpi3mr: Add helper functions to retrieve device objects
Add the following helper functions:
- Get the device's sas address by reading corresponding device's Device
page0
- Get the expander object from expander list based on expander's handle
- Get the target device object from target device list based on device's
sas address
- Get the expander device object from expander list based on expanders's
sas address
- Get hba port object from hba port table list based on port's port id
