In case of the i.MX8M power-domains (i.MX8MQ, MM, MN) there is only one power-domain for each device. Therefore the 'id' field in struct power_domain should always be zero. Currently if a power-domain is accessed after the initial bind, the 'id' field is left uninitialized. This didn't cause any problems until the following commits were introduced:9086b64ca0("power-domain: Add support for refcounting (again)")a785ef2448("imx: power-domain: Enable refcounting on imx8mp") Now the 'id' field gets accessed in the power_domain_off() sequence and the invalid value causes "Synchronous Abort" failures. This was observed on a i.MX8MM board when running "usb start" and then "usb stop". Fix this issue by setting power_domain->id to '0' in imx8m_power_domain_of_xlate().
