Re: [PATCH] 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.
