ARM: dts: am335x-icev2: Add SPI based NOR
Enable support for W25Q64CVSSIG which is a Winbond 64 Mbit SPI NOR. At boot you will see the following message: m25p80 spi1.0: found s25fl064k, expected w25q64 This is because the JEDEC ID for this chip is the same as s25fl064k. However, this should be harmless since both chips are essentially the same.
