mtd: rawnand: Ensure the nand chip supports cached reads

2023-10-16T08:47:22Z

Both the JEDEC and ONFI specification say that read cache sequential support is an optional command. This means that we not only need to check whether the individual controller supports the command, we also need to check the parameter pages for both ONFI and JEDEC NAND flashes before enabling sequential cache reads. This fixes support for NAND flashes which don't support enabling cache reads, i.e. Samsung K9F4G08U0F or Toshiba TC58NVG0S3HTA00. Sequential cache reads are now only available for ONFI and JEDEC devices, if individual vendors implement this, it needs to be enabled per vendor. Tested on i.MX6Q with a Samsung NAND flash chip that doesn't support sequential reads.
