[V5,10/13] PCI: tegra194: Apply pinctrl settings for both PCIe RP and EP

[Manikanta Maddireddy]

From: Vidya Sagar <vidyas@xxxxxxxxxx>

PERST# and CLKREQ# pinctrl settings should be applied for both root port
and endpoint mode. Move pinctrl_pm_select_default_state() function call
from root port specific configuration function to probe().

Fixes: c57247f940e8 ("PCI: tegra: Add support for PCIe endpoint mode in Tegra194")
