This patchset introduces some minor fixes for v1 hw
itct configuration.
John Garry (3):
hisi_sas: fix v1 itct masks
hisi_sas: fix typo in setup_itct_v1_hw()
hisi_sas: use u64 for qw0 in free_device_v1_hw()

The mask fields are for quad-words, so add ULL suffix.
Also unreferenced ITCT_HDR_BREAK_REPLY and
ITCT_HDR_MAX_BURST are removed.

We were doing a arithmetic comparison instead
of logical shift by accident.
Mis-programming the itct did not seem to make
a difference to operation.

By reading in itct.qw0 into a 32b variable the top
32 bits were being lost.
In practice this was OK as they were zeroes.
