serial: imx: Restore original RXTL for console to fix data loss
Commit 7a637784d517 ("serial: imx: reduce RX interrupt frequency")
introduced a regression on the i.MX6UL EVK board. The issue can be
reproduced with the following steps:
- Open vi on the board.
- Paste a text file (~150 characters).
- Save the file, then repeat the process.
- Compare the sha256sum of the saved files.
The checksums do not match due to missing characters or entire lines.
Fix this by restoring the RXTL value to 1 when the UART is used as a
console.
This ensures timely RX interrupts and reliable data reception in console
mode.
With this change, pasted content is saved correctly, and checksums are
always consistent.
