mtd: ST SPEAr: Add SMI driver for serial NOR flash
SPEAr platforms (spear3xx/spear6xx/spear13xx) provide SMI (Serial Memory Interface) controller to access serial NOR flash. SMI provides a simple interface for SPI/serial NOR flashes and has certain inbuilt commands and features to support these flashes easily. It also makes it possible to map an address range in order to directly access (read/write) the SNOR over address bus. This patch intends to provide serial nor driver support for spear platforms which are accessed through SMI.
