pinctrl: ocelot: Fix alt mode for ocelot

Browse source

[ Upstream commit 657fd9da2d ]

In case the driver was trying to set an alternate mode for gpio
0 or 32 then the mode was not set correctly. The reason is that
there is computation error inside the function ocelot_pinmux_set_mux
because in this case it was trying to shift to left by -1.
Fix this by actually shifting the function bits and not the position.
