The N25Q256(A) datasheet clearly states that this device does have
a Flag Status Register and does update FSR PEC bit 7 during Program
and Erase cycles to indicate the cycle is in progress. Enable the
FSR PEC bit polling on this device to prevent data corruption.

mtd: nand: mxs_nand_spl: add mxs_flash_full_ident

For now, the existing SPL MXS NAND driver only supports to identify
ONFi-compliant NAND chips. In order to allow identifying
non-ONFi-compliant chips add `mxs_flash_full_ident()` which uses the
`nand_get_flash_type()` functionality from `nand_base.c` to lookup
for supported NAND chips in the chip ID list.

For compatibility reason the full identification support is only
available if the config option `CONFIG_SPL_NAND_IDENT` is enabled.

The lookup was tested on a custom i.MX6ULL board with a Toshiba
TC58NVG1S3HTAI0 NAND chip.

The existing `mxs_flash_ident()` is limited to identify ONFi compliant
NAND chips only. In order to support non-ONFi NAND chips refactor the
function and rename it to `mxs_flash_onfi_ident()`.

A follow-up patch will add `mxs_flash_full_ident()` which allows to use
the chip ID list to lookup for supported NAND flashs.

`nand_get_flash_type()` allows identification of supported NAND flashs.
The function is useful in SPL (like mxs_nand_spl.c) to lookup for a NAND
flash (which does not support ONFi) instead of using nand_simple.c and
hard-coding all required NAND parameters.

mtd: nand: mxs_nand: add support for specific ECC strength

Add support for specified ECC strength/size using device tree
properties nand-ecc-strength/nand-ecc-step-size.

This aligns behavior with the mainline driver, such that:
- If fsl,use-minimal-ecc is requested it will use data from
  data sheet/ONFI. If this is not available the driver will fail.
- If nand-ecc-strength/nand-ecc-step-size are specified those
  value will be used.
- By default maximum possible ECC strength is used
