Jason-JH Lin 3196b6c708 mailbox: mtk-cmdq: Refine GCE_GCTL_VALUE setting
[ Upstream commit 9fcebcb37c ]

Add cmdq_gctl_value_toggle() to configure GCE_CTRL_BY_SW and GCE_DDR_EN
together in the same GCE_GCTL_VALUE register.

For the SoCs whose GCE is located in MMINFRA and uses MMINFRA_AO power,
this allows it to be written without enabling the clocks. Otherwise, all
GCE registers should be written after the GCE clocks are enabled.
Move this function into cmdq_runtime_resume() and cmdq_runtime_suspend()
to ensure it is called when the GCE clock is enabled.
