hw/ssi: Allwinner A10 SPI emulation

This patch implements Allwinner A10 SPI controller emulation.
Only master-mode functionality is implemented.

Since U-Boot and Linux SPI drivers for Allwinner A10 perform only
byte-wide CPU access (no DMA) to the transmit and receive registers of
the peripheral, the emulated controller does not implement DMA control,
and supports only byte-wide access to transmit and receive registers
(half-word and word accesses will be treated as byte accesses).

hw/ssi: Add SPI model

SPI controller device model supports a connection to a single SPI responder.
This provide access to SPI seeproms, TPM, flash device and an ADC controller.

All SPI function control is mapped into the SPI register space to enable full
control by firmware. In this commit SPI configuration component is modelled
which contains all SPI configuration and status registers as well as the hold
registers for data to be sent or having been received.

An existing QEMU SSI framework is used and SSI_BUS is created.

aspeed/smc: Improve support for the alternate boot function

Map the WDT2 registers in the AST2600 FMC memory region by creating a
local address space on top of WDT2 memory region.

The model only implements the enable bit of the control register. The
reload register uses a 0.1s unit instead of a 1us. Values are
converted on the fly when doing the accesses. The restart register is
the same.

TODO: This needs a rework since the FMC WDT2 device is an independent
watchdog logic embedded in the FMC device.

This implements a device model for the NPCM7xx SPI flash controller.

Direct reads and writes, and user-mode transactions have been tested in
various modes. Protection features are not implemented yet.

All the FIU instances are available in the SoC's address space,
regardless of whether or not they're connected to actual flash chips.

aspeed/smc: Fix DMA support for AST2600

Recent firmwares uses SPI DMA transfers in U-Boot to load the

FMC model is missing the masks to be applied on the DMA registers
which resulted in incorrect values. Fix that and wire the SPI
controllers which have DMA support on the AST2600.
