MLK-13186-2 arm: imx6qp: add imx6qp standalone pcie dtb
In order to pass the pcie gen2 compliance tests on imx6qp
sd revb board, add one standalone imx6qp sd ldo pcie dtb
- disalbe fec/sata, because that the fec/sata can't work
when pll6 is in bypass mode.
NOTE: Bypass mode of pll6 is mandatory required when
external oscillator is used as pcie ref clk.
