When PCIe link is disabled or secondary bus reset is done by RP, EP LTSSM state goes to link disable or hot reset respectively. Update the LTSSM state check accordingly to support link disable and secondary bus reset. XTL_EP_PRI_BAR_CONFIG and XTL_EP_PRI_RESIZE_BAR1 are part of hot reset domain, when link is going through hot reset, these registers are not accessible. So, remove these register programming in tegra264_pcie_ep_clear_bar(). After hot reset these registers come back with reset values.
