[PATCH] dt-bindings: fix compilation error of the example in marvell,mmp3-hsic-phy.yaml

[Dafna Hirschfeld]

Running `make dt_binging_check`, gives the error:

DTC     Documentation/devicetree/bindings/phy/marvell,mmp3-hsic-phy.example.dt.yaml
Error: Documentation/devicetree/bindings/phy/marvell,mmp3-hsic-phy.example.dts:20.41-42 syntax error
FATAL ERROR: Unable to parse input tree

This is because the example uses the macro GPIO_ACTIVE_HIGH which
is defined in gpio.h but the include of this header is missing.
Add the include to fix the error.
