firmware: imx: scu: manage mailbox channels and global handle

Browse source

imx_scu_probe() requests mailbox channels with the non-managed
mbox_request_channel_byname() helper and then publishes sc_ipc through
the global imx_sc_ipc_handle.  Later probe failures, including child
population failure, can leave the channels and global handle live after
the probe has failed.

Register devres actions to free each mailbox channel and clear the global
handle.  Also depopulate partially created child devices when
devm_of_platform_populate() reports an error.
