The HiSilicon SAS HBA is available in HiSilicon arm64 SoCs only.
Restrict it to arm64, unless compile-testing.

Add a dependency on HAS_DMA to fix this.

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.
