serial: tegra: add serial driver

NVIDIA's Tegra has multiple UART controller which supports:
- APB DMA based controller fifo read/write.
- End Of Data interrupt in incoming data to know whether end
  of frame achieve or not.
- HW controlled RTS and CTS flow control to reduce SW overhead.

Add serial driver to use all above feature.
