Series of patches adding enhancements to exising UART driver and adding
support for new chip Tegra186 and Tegra194.
Tegra186 uses GPCDMA for dma transfers which is still not available in
mainstream. However, it can work in PIO/FIFO mode and support added for it.
Also Tegra186 has a hardware issue where it does not meet tolernace +/-4% and
to work around it, device tree entries provided to adjust baud rate for a
particular range.

Changes from V1:
Consistent spellings and few other cosmetic changes.
Do not ignore sysrq request when ignoring reads.
Remove WARN_ON for errors that are user triggered.
Fix max ports for Tegra186 and Tegra194
Register uart driver in init by reading max ports from dt.
Rename burst size and wait api for FIFO enable.
