John Garry a8d547bd93 hisi_sas: set max commands as configurable
Since v2 hardware permits different numbers of commands to v1, set this
as configurable in hisi_sas_hw.

John Garry 0f28ede906 hisi_sas: fix v1 hw check for slot error
Completion header bit CMPLT_HDR_RSPNS_XFRD flags whether the response
frame is received into host memory, and not whether the response frame
has an error.  As such, change the decision on whether a slot has an
error.  Also redundant check on CMPLT_HDR_CMD_CMPLT_MSK is removed.

John Garry 4e09bff330 hisi_sas: Use u64 for qw0 in free_device_v1_hw()
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.

John Garry 8fb88201b4 hisi_sas: Fix typo in setup_itct_v1_hw()
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.

irq_of_parse_and_map(), so replace.

John Garry 8c77dca011 hisi_sas: Remove dependency on of_irq_count
Originally the driver would use of_irq_count to calculate how much
memory is required for storing the interrupt names, since the number of
interrupt sources for the controller is variable.  Since of_irq_count
cannot be used by the driver, use fixed names.
