hisi_sas: Add initial bare main driver 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.

scsi: hisi_sas: Remove depends on HAS_DMA in case of platform dependency Remove dependencies on HAS_DMA where a Kconfig symbol depends on another symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST". In most cases this other symbol is an architecture or platform specific symbol, or PCI. Generic symbols and drivers without platform dependencies keep their dependencies on HAS_DMA, to prevent compiling subsystems or drivers that cannot work anyway. This simplifies the dependencies, and allows to improve compile-testing.

scsi: hisi_sas: fix SATA dependency Removing the 'select SCSI_SAS_LIBSAS' statement in Kconfig resulted in a link failure in configurations that have hisi_sas built-in but libsas as a loadable module: drivers/scsi/built-in.o: In function `hisi_sas_scan_finished': hisi_sas_main.c:(.text+0x37ce9): undefined reference to `sas_drain_work' drivers/scsi/built-in.o: In function `hisi_sas_slave_configure': hisi_sas_main.c:(.text+0x37d17): undefined reference to `sas_slave_configure' hisi_sas_main.c:(.text+0x37d40): undefined reference to `sas_change_queue_depth' drivers/scsi/built-in.o: In function `hisi_sas_remove': All other libsas users have the 'select' statement, so we should do the same here for consistency. For all I can tell, the patch that added the sata softreset does not actually introduce a dependency on SCSI_SAS_ATA but instead adds calls into libata itself, so we can express that with a more specific dependency. We cannot have 'select SCSI_SAS_LIBSAS; depends on SCSI_SAS_ATA' as that would cause a dependency loop.
