[PATCH] remoteproc: adopt the driver core's alloc/add/del/put naming

[Ohad Ben-Cohen]

To make remoteproc's API more intuitive for developers, we adopt
the driver core's naming, i.e. alloc -> add -> del -> put. We'll also
add register/unregister when their first user shows up.

Otherwise - there's no functional change here.

Suggested by Russell King <linux@xxxxxxxxxxxxxxxx>.
