[PATCH v2 04/17] board: cssi: Initialise port F on MIAE

From: Hugo Dubois <hugo.dubois.ext@csgroup.eu>

When equipped with the SRSA audio board, MIAE equipment
has an additional port called port F.

Initialise that port just like other ports of the board, so
that it is already configured when starting Linux kernel.
