[PATCH 1/3] dt-bindings: dsp: support imx8ulp dsp clocks

[Laurentiu Mihalcea <laurentiumihalcea111@gmail.com>]

From: Laurentiu Mihalcea <laurentiu.mihalcea@nxp.com>

i.MX8ULP DSP node needs a MU clock, but doesn't need
a debug clock. Change "clocks" and "clock-names" properties
to allow for this case.
