[PATCH v2] mtd: spi-nor: Add support for cy15x104q

[Sascha Hauer <s.hauer@xxxxxxxxxxxxxx>]

The Cypress cy15b104q and cy15v104q are 4Mbit serial SPI F-RAM devices.
Add support for them to the spi-nor driver.

Changes since v1:
- Instead of specifying 1024 sectors with a sector size of 512 specify
  512 * 1024 sectos with a sector size of 1. The device has no idea of
  sectors and is not erasable, so a sector size of 1 seems to better
  reflect reality.
