Freescale i.MX8qm/qxp CSR module matches with what the simple power
managed bus driver does, considering it needs an IPG clock to be
enabled before accessing it's child devices, the child devices need
to be populated by the CSR module and the child devices' power
management operations need to be propagated to their parent devices.
Add the CSR module's compatible strings to simple_pm_bus_of_match[]
table to support the CSR module.
