greybus: operation: allow drivers to define custom timeouts
Add new interface gb_operation_request_send_sync_timeout, which allows
drivers to define a custom operation timeout instead of the default
one-second timeout.
The timeout is expected to depend on protocol and operation and
therefore needs to be configurable.
Note that that a timeout of zero is used to wait indefinitely.
