spi: npcm-fiu: add NPCM FIU controller driver
Add Nuvoton NPCM BMC Flash Interface Unit(FIU) SPI master controller driver using SPI-MEM interface. The FIU supports single, dual or quad communication interface. the FIU controller can operate in following modes: - User Mode Access(UMA): provides flash access by using an indirect address/data mechanism. - direct rd/wr mode: maps the flash memory into the core address space. - SPI-X mode: used for an expansion bus to an ASIC or CPLD.
