pinctrl: sunxi: only use PortK special handling on A523

Browse Source 
The Allwinner A523 pinctrl IP requires an exception for addressing PortK,
since the registers for this GPIO bank did not fit anymore in the
existing MMIO frame. Since the A523 was also the first SoC to actually
implement PortK, we just enabled this quirk unconditionally.
Now the new Allwinner A733 changed the MMIO frame layout, so PortK can
and must be handled without any special code.

Mark the special casing for PortK with the ELEVEN_BANKS quirk flag we
introduced, so that it will only be used on SoCs using the A523 pinctrl
IP.
