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.

File hisi_sas_pci_init.c is introduced for pci device probing
and initialization. Common functionality is still in
hisi_sas_main.c, along with platform device probing and
initialization.

New hw layer file hisi_sas_v3_hw.c is added for hip08
controller support. HW revisions v2 and v3 are very similar,
but it was decided to keep support in separate files for now.

As for the patches, (ignoring #1 and #2) 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.
