dt-bindings: display: fsl,imx6-hdmi: Change to 'unevaluatedProperties: false'

fsl,imx6-hdmi.yaml makes a reference to synopsys,dw-hdmi.yaml.

The 'interrupts' and 'reg' properties are described in synopsys,dw-hdmi.yaml,
so use 'unevaluatedProperties: false' so that these two properties can
be accepted.

This fixes the following schema warnings:

hdmi@120000: 'interrupts', 'reg' do not match any of the regexes: 'pinctrl-[0-9]+'
