Subject: [PATCH] mailbox: imx: use device name in interrupt name

From: Peng Fan <peng.fan@....com>

There are several MUs for different usage, SCMI MU, ELE MU, RemotePROC
MU. Using "imx_mu_chan" in interrupt name would be hard to identify
which MU triggers interrupt, so use device name to make it easy to know
which MU triggers which interrupt.
