From: Konrad Dybcio <konrad.dybcio@xxxxxxxxxxxxxxxx>
The GPU clock is required for CPU access to GPUSS registers. It was
previously decided (on this and many more platforms) that the added
overhead/hassle introduced by keeping track of it would not bring much
measurable improvement in the power department.
The display clock is basically the same story over again.
Now, we're past that discussion and this commit is not trying to change
that. Instead, the clocks are both force-enabled in .probe *and*
registered with the common clock framework, resulting in them being
toggled off after ignore_unused.
Unregister said clocks to fix breakage when clk_ignore_unused is absent
(as it should be).
Fixes: 161b7c401f4b ("clk: qcom: Add Global Clock controller (GCC) driver for X1E80100")
