## Summary

Removes the unnecessary wait for `TX EMPTY` in the printk out path.

According to the documentation, `TXRDY` indicates the output buffer is ready to receive data.

This change saves a bit of time in `printk`'s but more so just removes an unnessesary check not required by the hardware.

Added some formatting clean-up and clearer documentation for the same file along with this MR.

Tested on TMS570 LC43.

## Generative AI

None

Fixes #5553
