clk: mediatek: Fix error handling in runtime PM setup

Browse source

[ Upstream commit aa2ad19210 ]

devm_pm_runtime_enable() can fail due to memory allocation. The current
code ignores its return value, and when pm_runtime_resume_and_get() fails,
it returns directly without unmapping the shared_io region.

Add error handling for devm_pm_runtime_enable(). Reorder cleanup labels
to properly unmap shared_io on pm_runtime_resume_and_get() failure.
