It should include most flash drivers in the future. Though no uclass ops are defined yet, the MTD ops could be used. The NAND flash driver is based on MTD. The CFI flash and SPI flash support MTD, too. It should make sense to convert them to MTD uclass. Signed-off-by: Thomas Chou <thomas@wytron.com.tw>

Since commit 09c3280754f8 (mtd, nand: Move common functions from
cmd_nand.c to common place), NAND commands would not work at all
on large devices.

    => nand read 80000000 10000 10000

    NAND read: Offset exceeds device limit
    => nand erase 100000 100000

    NAND erase: Offset exceeds device limit

The type of the "size" of "struct mtd_info" is uint64_t, while
mtd_arg_off_size() and mtd_arg_off() treat chipsize as int type.
The chipsize is wrapped around if the argument is given with 2GB
or larger.
