intel/apollolake: Add IPU to disable_dev function
The SoC has an Image Processing Unit which is located on PCI 00:03.0.
There is a corresponding parameter for FSP which handles
enabling/disabling of this functionality (IpuEn). Add this device to
the disable_dev() function of the chip so that if this device is
disabled in devicetree the matching FSP parameter will be disabled as
well. As this parameter is only valid for Apollo Lake, use the config
switch CONFIG_SOC_INTEL_GLK to disable this code if compiled not for
Apollo Lake. As this issue is regarding a missing structure member,
this check needs to be done on preprocessor level and not at runtime.
Test=Verified this function on mc_apl2.
