Commit7a637784d5("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.
