hisi_sas: use device linkrate in MCR for v2 hw
Contrary to the field name, the MCR (max connection rate) in the ITCT should hold the device linkrate (linkrate of the connected phy), and not the max linkrate. This fixes an issue seen where some SATA drives connected through an expander which would not attach.
