[PATCH 11/13] clk: mediatek: reset: Implement mtk_unregister_reset_controller() API

[Yassine Oudjana <yassine.oudjana@gmail.com>]

From: Yassine Oudjana <y.oudjana@protonmail.com>

Add a function to unregister a reset controller previously
registered with mtk_register_reset_controller() or
mtk_register_reset_controller_set_clr(), and do the necessary cleanup.
