Mark switch cases where we are expecting to fall through.

drivers/mtd/maps/sa1100-flash.c:82:3: warning: this statement may fall through [-Wimplicit-fallthrough=]
   printk(KERN_WARNING "SA1100 flash: unknown base address "
   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
          "0x%08lx, assuming CS0\n", phys);
          ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
