PEI Chipset Services driver.
It produces an instance of the PEI Chipset Services PPI to provide the chipset related functions
which will be used by Kernel or Project code. These PPI functions should be used by calling the
corresponding functions in PeiChipsetSvcLib to have the protocol size checking
