arm: imx: rename the compatible node of lpm mu driver

Browse Source 
Because that the mailbox MU driver is used in i.MX RPMSG implementation.
There is a confliction between this MU driver and the mailbox MU driver.

To back-compaible with LPM of iMX6SX, iMX7D and iMX7ULP.
Rename the compatible node of this MU driver.
