hisi_sas: Allocate memories and create pools
Allocate DMA and non-DMA memories for the controller. Also create DMA
pools.
These include:
- Delivery queues
- Completion queues
- Command status buffer
- Command table
- ITCT (For device context)
- Host slot info
- IO status
- Breakpoint
- host slot indexing
- SG data
- FIS
- interrupts names
