util/ifdtool: Use -p platform name to detect IFDv2 platform and chipset
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.

TEST=Able to dump FD contains correctly with platform quirks on Brya Platform.
