mtd: st_spi_fsm: Provide device look-up table
Supply a lookup table of all the devices we intend to support. This table is used to store device information such as; a human readable device name, their JEDEC ID (plus the extended version), sector size and amount, a bit store of a device's capabilities, its maximum running frequency and possible use of a per-device configuration call-back.
