[PATCH 02/30] mtd: spi-nor: winbond: Normalize names

[Miquel Raynal]

Winbond chips cannot just be named eg. "W25Q02JV". There are always more
letters after that name, some of them matter.

- W is the Winbond prefix
- 25Q is the type of device
  -> 25Q indicates a quad capable SPI NOR
  -> 25H indicates an automotive grade chip
- 02J is the density
  -> in this case 2Gib
- V is the voltage
  -> V means 3.3V
  -> W means 1.8V
- The next letters (either 2 or 3 letters) are completely irrelevant for
  the software and purely indicate the hardware package.
- The penultimate letter is the temperature grade
  -> I for Industrial grade
  -> J means "above" industrial
- Q, N or M indicate factory states (like QE=1) and also the DTR
  capability.
  -> Q and N typically have the same IDs
  -> M chips typically have a different ID

As a result, W25Q01NWxxIQ is irrelevant and would better be named
W25Q01NW-Q, W25Q02JV is irrelevant and would better be named W25Q02JV-M,
etc.

Make that list uniform before adding more IDs/names.
