This patch adds a new pinmux for UART2, which shares the pins with SPIS.

Thanks. AFAIK, this will not be used by any of the currently supported
boards. Is this correct?

Mauro is currently trying to port mainline U-Boot to the VoCore2 board
which also uses UART2. I did not look to close, but might this pin mux
option here be necessary for this VoCore2 board?

Thanks,
Stefan
