soc/intel/icelake: Skip FSP-S IGD related UPD override
Default FSP values for "GtFreqMax" and "CdClock" UPDs are "Auto", hence
related FSP-S UPD override can be avoided from coreboot.
As per FSP-S UPD Header (FspsUpd.h)
/** Offset 0x020E - GT Frequency Limit
0xFF: Auto(Default)
**/
UINT8 GtFreqMax;
/** Offset 0x0209 - CdClock Frequency selection
0: (Default) Auto
**/
UINT8 CdClock;
TEST=Able to get Pre-OS display on ICLRVP and Dragonegg platform.
