LF-290 PCI: imx: add the pcie pm workaround for imx6qdl Add the PCIe PM workaround for iMX6QDL. ------ L2 can exit by 'reset' or inband beacon (from remote EP) toggling phy_powerdown has same effect as 'inband beacon' So, toggle bit18 of GPR1, used as a workaround of errata ERR005723 "PCIe PCIe does not support L2 Power Down" WARNING: This is not official workaround for ERR005723. Fortunately, we don't encounter issue with this workaround. User should take own risk to use it. Signed-off-by: Richard Zhu <hongxing.zhu@nxp.com> Reviewed-by: Fugang Duan <fugang.duan@nxp.com>
