[U-Boot] [PATCH v2 02/10] arm: mach-k3: am6_init: Initialize AVS class 0

Initialize AVS class 0 so that mpu voltage rail is
programmed to the AVS class 0 compensated value.

Changes in v2:

  * Now that AVS is misc device do not go by default ID 0
    and rely on uclass_get_device_by_driver to get the right device.
