hw/ssi: NPCM7xx Flash Interface Unit device model

Browse source 
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.
