SPI NOR changes for 6.12

Notable changes:

- Add Write Protect support for N25Q064A.

- New flash support for Zetta ZD25Q128C and Spansion S28HS256T.

- Fix a NULL dereference in probe path for flashes without a name. The
  probe path tries to access the name without checking its existence
  first. S28HS256T is the first flash to define its entry without a
  name, uncovering this issue.
