Subject: [PATCH 2/3] arm64: dts: mediatek: mt8173: Fix disp-pwm compatible string

The MT8173 disp-pwm device should have only one compatible string, based
on the following DT validation error:

    arch/arm64/boot/dts/mediatek/mt8173-elm.dtb: pwm@...1e000: compatible: 'oneOf' conditional failed, one must be fixed:
	    ['mediatek,mt8173-disp-pwm', 'mediatek,mt6595-disp-pwm'] is too long
	    'mediatek,mt8173-disp-pwm' is not one of ['mediatek,mt6795-disp-pwm', 'mediatek,mt8167-disp-pwm']
	    'mediatek,mt8173-disp-pwm' is not one of ['mediatek,mt8186-disp-pwm', 'mediatek,mt8188-disp-pwm', 'mediatek,mt8192-disp-pwm', 'mediatek,mt8195-disp-pwm', 'mediatek,mt8365-disp-pwm']
	    'mediatek,mt8173-disp-pwm' was expected
	    'mediatek,mt8183-disp-pwm' was expected
	    from schema $id: http://devicetree.org/schemas/pwm/mediatek,pwm-disp.yaml#
    arch/arm64/boot/dts/mediatek/mt8173-elm.dtb: pwm@...1f000: compatible: 'oneOf' conditional failed, one must be fixed:
	    ['mediatek,mt8173-disp-pwm', 'mediatek,mt6595-disp-pwm'] is too long
	    'mediatek,mt8173-disp-pwm' is not one of ['mediatek,mt6795-disp-pwm', 'mediatek,mt8167-disp-pwm']
	    'mediatek,mt8173-disp-pwm' is not one of ['mediatek,mt8186-disp-pwm', 'mediatek,mt8188-disp-pwm', 'mediatek,mt8192-disp-pwm', 'mediatek,mt8195-disp-pwm', 'mediatek,mt8365-disp-pwm']
	    'mediatek,mt8173-disp-pwm' was expected
	    'mediatek,mt8183-disp-pwm' was expected
	    from schema $id: http://devicetree.org/schemas/pwm/mediatek,pwm-disp.yaml#

Drop the extra "mediatek,mt6595-disp-pwm" compatible string.
