...because working zoom2 UART support was not yet upstream.

Using FOURPORT isn't right either. Just use a number.
If you're OK with the version below, I'll pull it into my fixes queue.
I've also updated the changelog to explain the problem instead of just
"fix the break..." This fix messages are not useful when looking back
through the changelog history.
I don't currently have access to a Zoom2, so this has not been tested.

OMAP: Zoom2: update serial platform_data id for external UART
Now that on-chip UARTs each have separate platform_data, the external
UART needs an non-conflicting ID. Since there are 3 on-chip UARTs,
the Zoom2 external UART will be registered after as the fourth.
