Add binding documentation for SPI controller in Qualcomm Atheros AR934x/QCA95xx SoCs. Signed-off-by: Chuanhong Guo <gch981213@xxxxxxxxx> --- Change since v3: replace clock binding with ath79 pll as this is the actual clock binding used in all SoC supported by this driver. Change since v2: replace clock binding in example with a bogus spi_clock to fix dt binding check error.
