Intel TGL BIOS specification (doc ##611569) Revision 0.7.6 Section
7.2.5.1.5 recommends reserving the following resources for each PCIe
USB4 root port:
- 42 buses
- 194 MiB Non-prefetchable memory
- 448 MiB Prefetchable memory
This change enables reserving of resources for USB4 when mainboard
selects the newly added Kconfig SOC_INTEL_ENABLE_USB4_PCIE_RESOURCES.
This is similar to the change for ADL in commit 8d11cdc6fa
("soc/intel/alderlake: Add Kconfig for recommended PCIe TBT resources").

Now that the PMC device is marked as hidden in devicetrees, the device
callbacks can be used instead of BOOT_STATE_INIT_ENTRY callbacks.
Note that this moves PMC initialization from BS_DEV_INIT_CHIPS to
BS_DEV_ENUMERATE, which aligns with other Intel SoCs.

Because Broadwell sets `duty_width` to 0, processor duty cycle is not
