PCI: imx6: Remove apps_reset toggling from imx_pcie_{assert/deassert}_core_reset

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.
