Looks typo. Replace ";" with ":" in commit header.

> 
> This patch creates a new macro to get PORT_TX register for any given DW.
> This removes the need of defining register address for each port & DW.
> 
> Changes since V1:
>  - Use underscope prefix, as macro isn't returning an mmio reg(Lucas)
>  - Merge patch 1 & 2 of the series
> Changes since V2:
>  - remove _MMIO_PORT6_LN macro (Rodrigo)
