mtd: nand: squash struct nand_buffers into struct nand_chip
struct nand_buffers is malloc'ed in nand_scan_tail() just for
containing three pointers. Squash this struct into nand_chip.
Move and rename as follows:
chip->buffers->ecccalc -> chip->ecc.calc_buf
chip->buffers->ecccode -> chip->ecc.code_buf
chip->buffers->databuf -> chip->data_buf
