[PATCH] serial/atmel_serial: Fix another fallout of the change to BUILD_BUG_ON

[Uwe Kleine-KÃnig]

Commit 8c87df457cb5 fixed BUILD_BUG_ON with the result that some
expressions (e.g. "not really constant" ones) result in a build failure.

Some of these were fixed in 8c87df457cb5, but not serial/atmel_serial.
