Pass the arguments in the communication buffer so that the SMI handler does not need to access arbitrary memory allocated by the SMMSTORE caller. It helps to isolate and restrict the memory accessed by SMM when STM is enabled. Signed-off-by: Michał Żygowski <michal.zygowski@3mdeb.com>

Reserving PCIe MMCONF on Intel systems causes issues with PCI aperture and causes the PCI drivers to fail, e.g. SATA controller driver cannot access its BARs, due to PCI memory aperture intersecting with reserved memory. Instead of marking the PCIe MMCONF as reserved memory, mark it as runtime MMIO so that it is passed to OS as reserved in memory map, but still visible as MMIO to EDK2 PCI driver. Now the EDK2 does not reject resources, does not indicate intersecting memory ranges, and the PCIe MMCONF is marked as reserved in the memory map passed to the OS. TEST=Run "fwts mcfg" command and pass the tests. Signed-off-by: Michał Żygowski <michal.zygowski@3mdeb.com>
