Since func nand_read_skip_bad is used in uboot, so just build it in
uboot build. And use func mtd_read to replace it.

Since mtd_read() can not skip bad block if meet bad block, so use
nand_read_skip_bad().

In the nand mtd, we will use chip info to operate nand, and get the chip
through mtd_to_nand(). So we should get mtd through dev_get_priv() but not
dev_get_uclass_platdata.

Reserve one block space for gpt table in mtd part info,
otherwise gpt table will be erased by user program.

The desc->lba is based on mtd->size: desc->lba = mtd->size >> 9;
If the mtd storage is spi nand or nand flash, reserve 4 blocks
for BBT(Bad Block Table). Then desc->lba is
desc->lba = (mtd->size >> 9) - (mtd->erasesize >> 9) * 4;

Attach the mtd driver to block device, then we can call common interface
(blk_dread & blk_dwrite) to operate storage in application layer.
Usage:
Open CONFIG_MTD_BLK & CONFIG_MTD.
