When asked to place cbmem_top(), FSP does not seem to care about
alignment. It can return an address that is MTRR poison, which will
exhaust all variable MTRRs when trying to set up caching for CBMEM.
This will make memory-mapped flash and TSEG caching fail as well.
Safeguard against this by aligning the region to cache to half of its
size, and move it upwards to compensate. It is assumed that caching
memory above the provided bootloader TOLUM address is inconsequential.

Initialize timestamp table with data from psp_verstage on bootblock.
PSP keeps its own timestamp and pass it in transfer_buffer. However PSP
timestamp and TSC may be out of sync so we can't just merge two tables
without modification.
info->timestamp contains PSP's clock value (in us) when x86 processor
released and base_timestamp contains TSC value when bootblock is
started. The time between x86 release and bootblock entry should be very
short so we can think those two happened at the same time and use them
for sync.
In some cases there will be underflow in timestamp entries but cbmem
utility can handle wrap-over in entries. Few timestamp values including
1st timestamp can be very large but we can still get the time spent on
boot without any problem.

Link time optimization is a technique for whole-program optimization.
Instead of doing code generation during compilation, the compiler saves
its intermediate representation to the object files. During the final
linking step, it will then merge all the object files together and
perform optimizations on the entire program. This can often reduce the
final binary size, but also may increase the total compilation time.
This patch introduces a Kconfig option for enabling link time
optimization in libpayload. Since libpayload does no linking of its own,
its LTO archive files will contain only IR and no generated code.
Downstream projects will need to use LTO-aware tools when manipulating
the archives (eg. gcc-ar and gcc-nm), but otherwise do not need to use
LTO themselves -- the compiler will recognize which files are LTO and
which are not, so enabling this option should mostly be "drop in".
For example, when building coreinfo.elf using tinycurses libpayload:
binary size compilation time
default 114 KiB 11.49s
LTO 95 KiB 10.36s
In this case the total compilation time was actually shorter -- despite
the final linking step taking longer, this was offset by the shorter
compilation times for each individual file (since there is no code gen
until the very end).

We can skip the PIT-based TSC calibration if we can derive the invariant
TSC rate from CPUID/MSR data. This is necessary if the PIT is disabled,
which is the default, for instance, on Coffee Lake CPUs.
This implementation should cover all Intel Core i processors at least.
For older processors, we fall back to the PIT calibration.
