Add I2S HS control instance to the sof core.
This will help the amd topology to use the I2S HS Dai.

Hello,
Since this patch was merged, SoundOpenFirmware stopped working on MediaTek MT8195,
as it fails on DAI component creation (firmware side)... check below...

@@ -84,6 +84,7 @@ enum sof_ipc_dai_type {
SOF_DAI_AMD_BT, /**< AMD ACP BT*/

SOF_DAI_AMD_DMIC, /**< AMD ACP DMIC */
+ SOF_DAI_AMD_HS, /**< Amd HS */
SOF_DAI_MEDIATEK_AFE, /**< Mediatek AFE */
Adding SOF_DAI_AMD_HS before SOF_DAI_MEDIATEK_AFE desynced this enumeration
so the DAI type is now 11 and not 10 anymore, leading to a failure in firmware
at IPC3 helper function `dai_get()`, as when `dai_find_type()` is called, the
DAI type that the firmware expects doesn't match with the one that gets sent
in the request message from the kernel.
As a local test, I tried moving SOF_DAI_AMD_HS after SOF_DAI_MEDIATEK_AFE and
this has restored full functionality on my MT8195 platform (Tomato Chromebook).
If SOF is supposed to guarantee backwards compatibility (and I believe it is),
this commit breaks that.
I would be tempted to send a commit that moves SOF_DAI_AMD_HS to the end, but
that would break the already compiled firmware for AMD platforms, so I am not
sure how to proceed.
So... how can we solve that?
Any ideas?
P.S.: Sharing some logs at the end of this email, just for completeness.
Best regards,
