hw/ssi: Extend SPI model
In this commit SPI shift engine and sequencer logic is implemented.
Shift engine performs serialization and de-serialization according to the
control by the sequencer and according to the setup defined in the
configuration registers. Sequencer implements the main control logic and
FSM to handle data transmit and data receive control of the shift engine.

aspeed/smc: support different memory region ops for SMC flash region
It set "aspeed_smc_flash_ops" struct which containing
read and write callbacks to be used when I/O is performed
on the SMC flash region. And it set the valid max_access_size 4
by default for all ASPEED SMC models.
However, the valid max_access_size 4 only support 32 bits CPUs.
To support all ASPEED SMC model, introduce a new
"const MemoryRegionOps *" attribute in AspeedSMCClass and
use it in aspeed_smc_flash_realize function.

aspeed/smc: support dma start length and 1 byte length unit
DMA length is from 1 byte to 32MB for AST2600 and AST10x0
and DMA length is from 4 bytes to 32MB for AST2500.
In other words, if "R_DMA_LEN" is 0, it should move at least 1 byte
data for AST2600 and AST10x0 and 4 bytes data for AST2500.
To support all ASPEED SOCs, adds dma_start_length parameter to store
the start length, add helper routines function to compute the dma length
and update DMA_LENGTH mask to "1FFFFFF" to support dma 1 byte
length unit for AST2600 and AST1030.
Currently, only supports dma length 4 bytes aligned.
