PCI: tegra194: Create debugfs directory only when CONFIG_PCIEASPM is enabled

Browse source

Previously, the debugfs directory was unconditionally created in
tegra_pcie_config_rp() regardless of the CONFIG_PCIEASPM setting.
This led to unnecessary directory creation when ASPM support was disabled
since only ASPM state count was exposed through debugfs.

Hence, move the debugfs directory creation into init_debugfs() which is
conditionally compiled based on CONFIG_PCIEASPM. This ensures that both
the directory and 'aspm_state_cnt' entry are only created when ASPM is
enabled and avoids cluttering debugfs with empty directories when ASPM is
disabled.
