serial: tegra_hsuart: Cleanups and bug fixes

tegra_start_tx was called directly by the serial core, as
well as from dma and serial interrupts to queue the next
block of data.  Separate out the "queue next data"
functionality into tegra_start_next_tx.

Also fixes TX PIO by adjusting FIFO sizes and prevents
last characters from getting lost by spinning on TEMT
before disabling clocks.
