PCI: tegra: Program PADS_REFCLK_CFG* registers with per-SoC values
The value that should be programmed into the PADS_REFCLK register varies per SoC. Fix the Tegra PCIe driver to program the correct values. Future SoCs will require different values in cfg0/1, so the two values are stored separately in the per-SoC data structures. For reference, the values are all documented in NV bug 1771116 comment 20. The ASIC team has validated all these values, except for the Tegra20 value which is simply left unchanged in this patch.
