Subject: [PATCH v2] mtd: spi-nor: winbond: Add support for w25q512jvq

Add support for w25q512jvq. This is of the same series chip with
w25q256jv, which is already supported, but with size doubled and
different JEDEC ID.

Tested on Intel whitley platform with dd from/to the flash for
read/write respectly, and flash_erase for erasing the flash.
