[PATCH 5/7] dt-bindings: pinctrl: add compatible for Allwinner A523/T527

[Andre Przywara <andre.przywara@arm.com>]

The A523 contains a pin controller similar to previous SoCs, although
using 10 GPIO banks (PortB-PortK), all of them being IRQ capable.
This introduces a new style of binding, where the pinmux values for each
pin group is stored in the new "allwinner,pinmux" property in the DT
node, instead of requiring every driver to store a mapping between the
function names and the required pinmux.

Add the new name to the list of compatible strings, and required it to
have 10 interrupts described. Also add the new pinmux property.
