soc/intel/alderlake: Add Kconfig for recommended PCIe TBT resources
The Intel ADL BIOS specification #627270 recommends reserving the
following resources for each PCIe TBT root port:
- 42 buses
- 192 MiB Non-prefetchable memory
- 448 MiB Prefetchable memory
Add a mainboard Kconfig which will auto-select these recommended values,
in addition to PCIEXP_HOTPLUG.
