mtd: spi-nor: winbond: Add support for W25H02NWxxAM chips

commit 604cf6a40157abba4677dea9834de8df9047d798 upstream.

These chips 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.
