commitd31eb21742upstream. apps_reset corresponds to LTSSM_EN in i.MX7, i.MX8MQ, i.MX8MM and i.MX8MP platforms. Since assertion/de-assertion of apps_reset is done in imx_pcie_ltssm_enable() and imx_pcie_ltssm_disable(), remove it from imx_pcie_assert_core_reset() and imx_pcie_deassert_core_reset(). This also fixes a failure in enumerating the PI7C9X2G608GP (hotplug) chip reliably on i.MX8MM, as reported by Tim. It should be noted that only i.MX7D, i.MX8MQ, i.MX8MM, and i.MX8MP platforms have the apps_reset logic, so this change doesn't have any effect on other platforms.
