The clk_disable_quirk and clk_enable_quirk should really be called pre_reset_quirk and post_reset_quirk to avoid confusion like we had with hdq1w reset. Let's also rename the related functions so the code is easier to follow. Note that we also have reset_done_quirk that is needed in some cases after checking the separate register for reset done bit.
