drm: zynqmp_dp: Use scope-based mutex helpers

Browse source

Convert most mutex_(un)lock calls to use (scoped_)guard instead. This
generally reduces line count and prevents bugs like forgetting to unlock
the mutex. I've left traditional calls in a few places where scoped
helpers would be more verbose. This mostly happens where
debugfs_file_put needs to be called regardless. I looked into defining a
CLASS for debugfs_file, but it seems like more effort than it's worth
since debugfs_file_get can fail.
