serial: tegra: report clk rate errors Standard UART controllers support +/-4% baud rate error tolerance. Tegra186 only supports 0% to +4% error tolerance whereas other Tegra chips support standard +/-4% rate. Add chip data for knowing error tolerance level for each soc. Creating new compatible for Tegra194 chip as it supports baud rate error tolerance of -2 to +2%, different from older chips.
