hisi_sas: fix v2 hw multiple SATA disk issue
Intermittently it is found that when multiple SATA disks are directly
connected to the host that some disks are not detected. The problem is
that all set bitfields in ENT_INT_SRC1 are cleared for all phys in
sata_int_v2_hw() - it should clear the set bit for the phy being
serviced.
Also unnecessary double-write to ENT_INT_SRC1 and ENT_INT_SRC_MSK1 is
removed (remaining writes are done at end label).
