apps_reset is LTSSM_EN on i.MX7, i.MX8MQ, i.MX8MM and i.MX8MP platforms. Since the assertion/de-assertion of apps_reset(LTSSM_EN bit) had been wrappered in imx_pcie_ltssm_enable() and imx_pcie_ltssm_disable(); Remove apps_reset toggle in imx_pcie_assert_core_reset() and imx_pcie_deassert_core_reset() functions. Use imx_pcie_ltssm_enable() and imx_pcie_ltssm_disable() to configure apps_reset directly. Fix fail[1] to enumerate reliably PI7C9X2G608GP (hotplug) at i.MX8MM, which reported By Tim.
