devm_platform_ioremap_resource()
Use the devm_platform_ioremap_resource() helper instead of
calling platform_get_resource() and devm_ioremap_resource()
separately

There is a potential execution path in which function
platform_get_resource() returns NULL. If this happens,
we will end up having a NULL pointer dereference.
Fix this by replacing devm_ioremap with devm_ioremap_resource,
which has the NULL check and the memory region request.
This code was detected with the help of Coccinelle.

Check for mbox_chan_ops structures that are only stored in the ops field
of a mbox_controller structure. This field is of type const struct
mbox_chan_ops *, so mbox_chan_ops structures having this property can be
declared as const.
Done using Coccinelle:
