Mailbox channel/client is conceptually done in two steps: selecting the channel and binding the selected to channel to a client. Channel selection is sometimes controller specific (pcc and omap are examples). The channel/client binding code is all the same. This small series de-duplicates and refactors the channel/client binding into a common framework function: "mbox_bind_client" which all of the channel selection mechanisms can use. I found this duplicate code while working on the support for Gunyah hypervisor message queues [1]. I've only been able to compile-test omap-mailbox and pcc, however it is a straightforward conversion here.
