Cyrille Pitchen 51cca920ce ARM: dts: at91: sama5d2_xplained: Add QSPI0 + SPI NOR memory nodes
This patch enables the QSPI0 controller, configures its pin muxing and
declares a jedec,spi-nor memory.

sama5d2 Xplained RevB and RevC use the Macronix MX25L25673G flash
memory which advertises a maximum frequency of 80MHz for Quad IO
Fast Read. Set the spi-max-frequency to 80MHz knowing that actually
the QSPI drver will set the SPI bus clock to 166MHz / 3 = 55.3MHz.
