spi/winbond: Add a test for block protection status bits

With refactoring out of the way we can add a test to make sure the
region<>bpbits mapping is correct. Indeed we found that a number of
configurations are incorrect.

The datasheets say that min/max bp values should protect either all or
none of the flash depending on the cmp and tb bits. However we currently
always return no protection for these values.

The test merely documents the current behavour, a fix will come in a
later commit.
