The HPM (Hardware Performance Monitor) support consists of almost 7 hundred lines that would be put on top of the base riscv-iommu emulation. To avoid clogging riscv-iommu.c, add a separated riscv-iommu-hpm file that will contain HPM specific code. We'll start by adding riscv_iommu_hpmcycle_read(), a helper that will be called during the riscv_iommu_mmio_read() callback. This change will have no effect on the existing emulation since we're not declaring HPM feature support.
