mtd: spi-nor: winbond: Add support for W25H512NWxxAM chips
commit f21d2c7d37553b24825918f2f61df123e182b712 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.
