soc/intel/adl: Move USB4 hotplug Kconfig to common
This change adds a new Kconfig `SOC_INTEL_ENABLE_USB4_PCIE_RESOURCES`
that can be selected by mainboard to reserve hotplug resources for
USB4 at the SoC level. `ADL_ENABLE_USB4_PCIE_RESOURCES` is dropped
from soc/intel/alderlake and instead the newly added Kconfig is now
used. This new Kconfig is added so that the same config can be used
across different platforms. In following changes, this Kconfig is
utilized by TGL as well.
