mailbox: imx: use devm_of_platform_populate()

The driver uses of_platform_populate() but does not remove the added
devices on removal. This can lead to "double devices" on module removal
followed by adding the module again.

Use devm_of_platform_populate() to remove the populated devices once the
parent device is removed.
