[PATCH] drm/amdgpu: fix i2s_pdata out of bound array access

[Vijendar Mukunda]

Fixed following Smatch static checker warning:

    drivers/gpu/drm/amd/amdgpu/amdgpu_acp.c:393 acp_hw_init()
    error: buffer overflow 'i2s_pdata' 3 <= 3
    drivers/gpu/drm/amd/amdgpu/amdgpu_acp.c:396 acp_hw_init()
    error: buffer overflow 'i2s_pdata' 3 <= 3
