leds: trigger: Introduce a MTD (NAND/NOR) trigger
This commit introduces a MTD trigger for flash (NAND/NOR) device
activity. The implementation is copied from IDE disk.
This trigger deprecates the "nand-disk" LED trigger, but for backwards
compatibility, we still keep the "nand-disk" trigger around.
The motivation for deprecating the "nand-disk" LED trigger is that
it only works for NAND drivers, whereas the "mtd" LED trigger
is more generic (in fact, "nand-disk" currently only works for
certain NAND drivers).
