This reverses the correct power-down sequence: with the power domain already removed, the subsequent clk_disable_unprepare() calls end up operating on clock-controller hardware that is no longer powered, which can hang or behave unpredictably. Reorder the calls so iris_disable_power_domains() runs after all three clocks are disabled, ensuring clocks are always turned off while their power domain is still active, and mirroring the reverse of the power-on sequence.
