In the NPCM FIU driver:

   - When the flash device is not memory-mapped, flash reads are performed
   using dedicated SPI flash read commands.
   - When the flash device is memory-mapped, reads are done directly
   through the memory window, with the FIU hardware automatically handling the
   necessary flash read commands in the background.

I will remove the unnecessary reg-names from npcm7xx dtsi file.

Thanks,

Tomer
