Add skeleton driver for v3 hw in hisi_sas_v3_hw.c
File hisi_sas_v3_hw.c will serve 2 purposes:
- probing and initialisation of the controller based on pci device
- hw layer for v3-based controllers
The controller design is quite similar to v2 hw in hip07.
However key differences include:
-All v2 hw bugs are fixed (hopefully), so workarounds are not required
-support for device deregistration
-some interrupt modifications
-configurable max device support

This patch adds the initial bare main driver for the HiSilicon SAS
HBA. This only introduces the changes to build and load the main driver
module.
The complete driver consists of the core main module and also a module
platform driver for driving the hw.
The HBA is a platform device.
