ifdtool uses `chipset` information to determine how certain straps are decoded. This has been used for IFDv1 platforms as well as IFDv2 platforms (CHIPSET_500_600_SERIES_TIGER_ALDER_POINT). IFDv2 platforms are all expected to pass in `-p` argument to identify the platform. This platform information can be used to identify the appropriate chipset information. For IFDv1 since `-p` argument is not provided, ifdtool needs to use certain fields in the descriptor (e.g. strap length) for unique identification of IFDv1 chipset. This change updates `check_ifd_version()` function to: 1. Determine if IFD version is v1 or v2 based on `-p` argument. If `-p` is not provided, it assumes that the platform is using IFDv1. 2. Based on IFD version, it calls either `ifd2_platform_to_chipset()` or `ifd1_guess_chipset()` to determine chipset information. This fixes the issue reported with CB:44815, where ifdtool is unable to identify Alder Lake chipsets.
