IFDv1 always has 8 regions, while IFDv2 always has 16 regions.
It's platform specific which regions are used or are reserved.
The 'SPI programming guide' as the name says is a guide only,
not a specification what the hardware actually does.
The best to do is not to rely on the guide, but detect how many
regions are present in the IFD and expose them all.
Very early IFDv2 chipsets, sometimes unofficially referred to as
IFDv1.5 platforms, only have 8 regions. To not corrupt the IFD when
operating on an IFDv1.5 detect how much space is actually present
in the IFD.
Fixes IFD corruption on Wellsburg/Lynxpoint when writing a new
flash layout.

`PLATFORM_IFD2` macro is more generic tag that can be associated with
early next SoC platform development which using IFDv2.
The current assumption is that newer SoC platform still uses the same
SPI/eSPI frequency definition being used for latest platform(TGL, ADL)
and if the frequency definition is updated later, `PLATFORM_IFD2' will
use latest frequency definition for early next SoC development.
And once upstream is allowed for new platform, platform name will be
added in tool later.

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.

We are implementing a mechanism in coreboot to update CSME firmware,
this requires coreboot to be able to read CSME region. Exposing the
CSME data is not an issue since the data stored by CSE is all encrypted.
This patch provides a command line option "-r" which will enable read
access to CSME region when locking.
Without this change, locking SPI regions using ifdtool will block BIOS
access to read/access CSME. This will cause failure since BIOS can't
