Make second parameter of ipc_msg_data generic

Add support of SOF on MediaTek MT8188 SoC.
MT8188 ADSP integrates with a single core Cadence HiFi-5 DSP.
The IPC communication between AP and DSP is based on shared DRAM and
mailbox interrupt.
The change in the mt8186.h is compatible on both mt8186 and
mt8188. The register controls booting the DSP core with the
default address or the user specified address. Both mt8186
and mt8188 should boot with the user specified boot in the driver.
The usage of the register is the same on both SoC, but the
control bit is different on mt8186 and mt8188, which is bit 1 on mt8186
and bit 0 on mt8188. Configure the redundant bit has noside effect
on both SoCs.

During suspend flow, sof_suspend will be called and the pm_ops->ctx_save

Before the DSP enter idle, an interrupt is generated to notify the host of
the power state change.
Since the host and DSP are two different processors, there could be a
race condition, which can be avoided by polling with 1s timeout and 500us
