This patchset adds support for the HiSilicon SAS controller
in the hip08 chipset.

The key difference compared to earlier chipsets is that the
controller is an integrated PCI endpoint in hip08.
As such, the controller is a pci device (not a platform device,
like v2 hw in hip07).

The driver is refactored so it can support both platform and 
pci device-based controllers.

New hw layer file hisi_sas_v3_hw.c is added for v3 hw
support, which also includes pci device proving and
initialisation. 

Common functionality is still in hisi_sas_main.c, along with
platform device probing and initialization.

As for the patches, (ignoring #1-3) the first few
reorganise some functions from v2 hw.c into main.c, as they
are required for v3 hw. Then support is added for pci
device-based controller in subsequent patches.
And then hip08 support is added in the final patches.

Difference to v4 series:
-report SAS_DATA_UNDERRUN to libsas for underflow

Differences to v3 series:
- Addressed Christoph's comments, including:
 - remove msi disable in probe, and improve irq
    registration and deregistration
 - remove hisi_sas_is_rw_cmd() to check underflow,
    and use scsi_cmnd underflow field instead

Differences to v2 series:
- Add patch to change hisi_sas_device.device_id size
- Add device dq pointer
- Remove hisi_sas_v3_hw prototype in v3 driver
- Add explicit comment in hisi_sas_get_fw_info()

Differences to v1 series:
- Addressed Arnd's comments, including:
 - read sas address from device node DSD under PCI host
    bridge
 - add comment in fatal axi error patch commit log regarding
    controller reset
 - eliminate hisi_sas_pci_init.c, and move functionality into
    hisi_sas_v3_hw.c, eliminating one layer of indirection
