mtd: nand: don't use read_buf for 8-bit ONFI transfers
Use a repeated read_byte() instead of read_buf(), since for x16 buswidth
devices, we need to avoid the upper I/O[16:9] bits. See the following
commit for reference:

mtd: nand: don't use {read,write}_buf for 8-bit transfers
Now, I think that all barriers to probing ONFI on x16 devices are
removed, so remove the check from nand_flash_detect_onfi().
Tested on 8-bit ONFI NAND (Micron MT29F32G08CBADAWP).
