lantiq: Backport upstream pinctrl-xway patches from 4.5
Upstream commit be14811c03cf2 "pinctrl/lantiq: introduce new dedicated devicetree bindings" allows us to use each pin in the pinmux. This is useful for example in the "spi" group which contains some pins which are inputs, and some which are outputs. These can only be used once the new compatible strings for the pinctrl node are used. Additionally 0150-lantiq-pinctrl-xway.patch and the "GPIO PORT3 fix" (which was part of 0012-pinctrl-lantiq-fix-up-pinmux.patch) were replaced with their upstream variants which are also in 4.5.
