fbdev: mmp: Use devm_clk_get_enabled() helpers
The devm_clk_get_enabled() helpers:
- call devm_clk_get()
- call clk_prepare_enable() and register what is needed in order to
call clk_disable_unprepare() when needed, as a managed resource.
This simplifies the code and avoids the calls to clk_disable_unprepare().
