ftsmc020: move ftsmc020 static mem controller to driver/mtd
Move the header file and definitions of ftsmc020 static memory control unit from a320 SoC folder to "drivers/mtd" folder. This change will let other SoC which also use ftsmc020 could share the same header file. Signed-off-by: Macpaul Lin <macpaul@andestech.com>
