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
