Subject: [PATCH v2 0/5] stm32-ddr-pmu driver creation

The DDRPERFM is the DDR Performance Monitor embedded in STM32MP1 SOC.

This series adds support for the DDRPERFM via a new stm32-ddr-pmu driver,
registered into the perf framework.

This driver is inspired from arch/arm/mm/cache-l2x0-pmu.c

---
Changes from v1:
- add 'resets' description (bindings) and using (driver). Thanks Rob.
- rebase on 5.2-rc1 (that includes the ddrperfm clock control patch).
