[PATCH] scsi: hisi_sas: redefine hisi_sas_phy.phy_type as u32

[John Garry]

Element phy_type is a bitmask and it only ever has 2
bits possibly set, and it is overkill to define as a u64,
so redefine as a u32.

This change resolves static code check complaint that
"phy->phy_type &= ~PORT_TYPE_SAS;" would
unintentionally clear the high 32 bits as well.

Structure hisi_sas_phy is also reordered to ensure
packing efficiency.
