PCI: tegra194: Set LTR message request before PCIe link up in Endpoint mode

LTR message should be sent as soon as the Root Port enables LTR in the
Endpoint mode. So set snoop and no-snoop LTR timing and LTR message request
before the PCIe link comes up, so that the LTR message is sent upstream as
soon as LTR is enabled.

Without programming these values, the Endpoint would send latencies of 0 to
the host, which will be inaccurate.
