clk: mediatek: Drop __initconst from gates
Description

In the Linux kernel, the following vulnerability has been resolved: clk: mediatek: Drop __initconst from gates Since commit 8ceff24a754a ("clk: mediatek: clk-gate: Refactor mtk_clk_register_gate to use mtk_gate struct") the mtk_gate structs are no longer just used for initialization/registration, but also at runtime. So drop __initconst annotations.

Solution
Remove __initconst annotations from mtk_gate structs in the Linux kernel.
  • Drop __initconst annotations from mtk_gate structs.
  • Ensure mtk_gate structs are not solely used for initialization.
  • Update struct usage for runtime access.
  • Apply the fix from commit 8ceff24a754a.
