MEMREAD is a new ioctl for MTD character devices that was first included
in Linux 6.1. It allows userspace applications to use the Linux
kernel's OOB autoplacement mechanism while reading data from NAND
devices. The Yafut tool needs this ioctl to do its job.

the OOB layout in MTK SNFI uses the 2nd byte, and anything using OOB
will make the block a bad-block in spi-nand driver.
Hack it for now. We need a proper solution upstream.
