Simplify framer_provider_simple_of_xlate() implementation by API
class_find_device_by_of_node().
Also correct comments to mark its parameter @dev as unused instead of
@args in passing.

Since commit 43a7206b09 ("driver core: class: make class_register() take
a const *"), the driver core allows for struct class to be in read-only
memory, so move the framer_class structure to be declared at build time
placing it into read-only memory, instead of having to be dynamically
allocated at boot time.

The xlate callbacks are supposed to translate of_phandle_args to proper
provider without modifying the of_phandle_args. Make the argument
pointer to const for code safety and readability.

A framer is a component in charge of an E1/T1 line interface.
Connected usually to a TDM bus, it converts TDM frames to/from E1/T1
frames. It also provides information related to the E1/T1 line.
The framer framework provides a set of APIs for the framer drivers
(framer provider) to create/destroy a framer and APIs for the framer
users (framer consumer) to obtain a reference to the framer, and
use the framer.
This basic implementation provides a framer abstraction for:
- power on/off the framer
- get the framer status (line state)
- be notified on framer status changes
- get/set the framer configuration
