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.
