Subject[PATCH] Revert "serial: 8250: Fix max baud limit in generic 8250 port"
From
This reverts commit 0eeaf62981ecc79e8395ca8caa1570eaf3a12257.

The change regresses the QCA6174A-3 bluetooth chip, preventing
firmware from being properly loaded. We have verified that without
this patch, the chip works as intended.
