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 v4:
- Change the enablement conditions of the Kconfig option so that
compilation is not performed in environments other than ARM64
(kernel test robot)
- Link to v3: https://lore.kernel.org/all/20250109054544.2342442-2-fj5100bi@fujitsu.com/
