So, in fact this patch shouldnt be needed. The LIME2 uses the dedicated
pins for HDMI DDC. PS2 0 pins PI20 and PI21 are in fact routed to
the GPIO-2 header. They are _not_ used for HDMI. Nothing bad should
happen unless you also multiplex PI20/PI21 to HSCL/HDSA.
If you check the schematics Olimex published and trace the HDMI lines,
you will see that this is the case.
