Subject: [PATCH 07/14] serial: tegra: add compatible for new chips

Add new compatible string for Tegra186. It differs from earlier chips
as it has fifo mode enable check and 8 byte dma buffer.
Add new compatible string for Tegra194. Tegra194 has different error
tolerance levels for baud rate compared to older chips.
