[PATCH v6 05/10] PCI: imx6: Make core reset assertion deassertion symmetric

Add apps_reset deassertion in the imx_pcie_deassert_core_reset(). Let it be
symmetric with imx_pcie_assert_core_reset().

In the commit first introduced apps_reset, apps_reset is asserted in
imx6_pcie_assert_core_reset(), but it is de-asserted in another place, in
stead of the according symmetric function imx6_pcie_deassert_core_reset().

Use this patch to fix it, and make core reset assertion deasertion
symmetric.
