c430cf376f mailbox: Fix devm_ioremap_resource error detection code
devm_ioremap_resource returns an ERR_PTR value, not NULL,
on failure.

The Coccinelle semantic patch used to make this change is
as follows:
@@
expression e,e1;
statement S;
@@

*e = devm_ioremap_resource(...);
if (!e1) S

bfbcfa770b mailbox: constify mbox_chan_ops structure
This mbox_chan_ops structure is never modified, so declare it as const,
like all the other mbox_chan_ops structures.

Done with the help of Coccinelle.

9ef4546cbd mailbox: Add support for ST's Mailbox IP
ST's platforms currently support a maximum of 5 Mailboxes, one for
each of the supported co-processors situated on the platform.  Each
Mailbox is divided up into 4 instances which consist of 32 channels.
Messages are passed between the application and co-processors using
shared memory areas.  It is the Client's responsibility to manage
these areas.
