Subject: [PATCH] media: iris: Fix power-off ordering to disable power domain
 after clocks

In iris_vpu_power_off_hw(), iris_disable_power_domains() was called
before the associated clocks (IRIS_BSE_HW_CLK, IRIS_HW_AHB_CLK,
IRIS_HW_CLK) were disabled and unprepared. 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.
