This adds two new dynamic PMUs to the Perf Events framework to program
and control the Uncore MAC/PCI PMUs in Fujitsu chips.

These drivers were created with reference to drivers/perf/qcom_l3_pmu.c.

These drivers export formatting and event information to sysfs so they can
be used by the perf user space tools with the syntaxes:

perf stat -e mac_iod0_mac0_ch0/ea-mac/ ls
perf stat -e mac_iod0_mac0_ch0/event=0x80/ ls

perf stat -e pci_iod0_pci0/ea-pci/ ls
perf stat -e pci_iod0_pci0/event=0x80/ ls

Changes in v3:
- Change to use CPUHP_AP_ONLINE_DYN for cpuhp state (Jonathan Cameron)
- Modify the code as suggested (Jonathan Cameron)
- Link to v2: https://lore.kernel.org/all/20241122061753.2598688-1-fj5100bi@fujitsu.com/
