Add dtsi for iMX6 Quad/Dual based SMARC SoM's from Kontron. The differences between the quad/dual and the dual-lite/solo are: * quad/dual has a 2nd IPU * quad/dual has three chip selects for SMARC SPI0 interface * quad/dual has a pcie_wake# signal Only the 3th spi-cs signal is added by this commit.
