scsi: hisi_sas: fix HBA SAS addr endianness for v1 hw
The endianness for the SAS address in the TX_ID_DWORD registers is set
incorrectly. We see errors like this in the boot log for v2 hw (which
would have the same issue as v1 hw):
[ 7.583284] sas: target proto 0x0 at 50000d1108e7923f:0x1f not handled
This is due to the host SAS addr not matching the PHY SAS addr in the
expander host-attached phy discovery responses.
To fix, we byte swap the SAS addr from BE to LE (which is the endianness
of the SAS controller).
