IFD2 platform already have use many plaforms which is not same as TGL,ADL.

static const int ifd_2_platforms[] = {
    PLATFORM_APL,
    PLATFORM_GLK,
    PLATFORM_CNL,
    PLATFORM_LBG,
    PLATFORM_ICL,
    PLATFORM_TGL,
    PLATFORM_JSL,
    PLATFORM_EHL,
    PLATFORM_ADL,
    PLATFORM_SKLKBL,
    PLATFORM_V1,
};

Will PLATFORM_IFD2_COMMON_V1 is better?
I think if there is new change for new platform we can use PLATFORM_IFD2_COMMON_V2 like this.

In that case we can use "ifd2_common_v1" or "ifd2_v1" as platform string.

What do you think?
