soc/intel/alderlake/hsphy: Add support for HSPHY firmware loading
BIOS must send the IP_LOAD HECI command to fetch the firmware for CPU
PCIe Gen5 and upload it via CPU REG BAR prior FSP Silicon Init.
Implementation based on public Slimbootloader's
"Silicon/AlderlakePkg/Library/CpuPcieHsPhyInitLib".
TEST=Boot MSI PRO Z690-A and see the HSPHY FW is loaded.
PCIe x16 Gen3 GPU card started working in the PCIE 5.0 slot.
[DEBUG] HECI: Sending Get IP firmware command
[DEBUG] HECI: Get IP firmware success. Response:
[DEBUG] Payload size = 0x6944
[DEBUG] Hash type used for signing payload = 0x3
