Subject: [PATCH 1/3] arm64: tegra: Fix Tegra194 HDA {clock,reset}-names ordering

As per the HDA binding doc reorder {clock,reset}-names entries for
Tegra194. This also serves as a preparation for converting existing
binding doc to json-schema.

-Required properties:

- must contain '"nvidia,<chip>-hda", "nvidia,tegra30-hda"', where <chip> is
- tegra114, tegra124, or tegra132.
-- reg : Should contain the HDA registers location and length.
-- interrupts : The interrupt from the HDA controller.
-- clocks : Must contain an entry for each required entry in clock-names.
- See ../clocks/clock-bindings.txt for details.
-- clock-names : Must include the following entries: hda, hda2hdmi, hda2codec_2x
-- resets : Must contain an entry for each entry in reset-names.
- See ../reset/reset.txt for details.
-- reset-names : Must include the following entries: hda, hda2hdmi, hda2codec_2x
