mtd: spi-nor: winbond: Add support for W25Q01NWxxIQ chips

commit aee8c4d9d48d661624d72de670ebe5c6b5687842 upstream.

This chip must be described as none of the block protection information
are discoverable. This chip supports 4 bits plus the top/bottom
addressing capability to identify the protected blocks.
