Hi,

Changelog

Patch nand_suspend() return error code to the upper layer,
removed _ prefix of suspend/resme hooks and kbuildtest robot tag.

  for protection function detection.
- patched the prefix for Macronix deep power down command, 0xB9
- Patched the description of mxic_nand_resume() and add a small sleeping 
  delay.
- Created a helper for deep power down device part number detection.

v2:
