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.
