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.
