MLK-9953 pcie: disable pcie on imx6sx platforms
The PCIe support in uboot would bring failures in i.MX6SX PCIe
EP/RC validations. Disable PCIe support in uboot here.
RootCause: The bit10(ltssm_en) of GPR12 would be set in uboot,
thus the i.MX6SX PCIe EP would be cheated that the other i.MX6SX
PCIe RC had been configured and trying to setup PCIe link
directly, although the i.MX6SX RC is not properly configured
at that time.
PCIe can be supported in uboot, if the i.MX6SX PCIe EP/RC
validation is not running.
