[PATCH v4] spi-nor: Add Winbond w25m512jv

[Joel Stanley]

From: Benjamin Herrenschmidt <benh at kernel.crashing.org>

Similar to the other ones, different size. The "JV" suffix is in
the datasheet, I haven't seen mentions of a different one.

The the datasheet indicates DUAL and QUAD are supported.
