The DFI unit can be used to measure DRAM utilization using perf. Add the
node to the device tree. The DFI needs a rockchip,pmu phandle to the pmu
containing registers for SDRAM configuration details. This is added in
this patch as well.

Look like the names never documented and nor supported explicitly in
the driver. Do we have any patch for fixing it in the mailing-list?

arch/arm64/boot/dts/rockchip/rk3588-edgeble-neu6b-io.dtb:
dfi@fe060000: 'interrupt-names' does not match any of the regexes:
'pinctrl-[0-9]+'
from schema $id: http://devicetree.org/schemas/devfreq/event/rockchip,dfi.yaml#
