dt-bindings: clock: imx8mp: Add #reset-cells property

The Audio Block Control contains clock distribution and gating
controls, as well as reset handling to several of the AUDIOMIX
peripherals. Especially the reset controls for Enhanced Audio
Return Channel (EARC) PHY and Controller.

So make Audio Block Control a reset provider for EARC, which
is one of modules in this audio subsystem.
