PM: Export AMBA bus type's default PM callbacks
Export the default PM callbacks defined for the platform bus type so
that they can be used by power domains for suspending and resuming
platform devices in the future.
Like 69c9dd1ecf446ad8a830e4afc539a2a1adc85b78 ("PM: Export platform bus
type's default PM callbacks").
