[PATCH v2 3/8] firmware: imx: scu-irq: Init workqueue before request mbox channel

[Peng Fan <peng.fan@nxp.com>]

With mailbox channel requested, there is possibility that interrupts may
come in, so need to make sure the workqueue is initialized before
the queue is scheduled by mailbox rx callback.
