iommu/riscv: Enable PT_FEAT_DETAILED_GATHER and pass gather to iotlb_inval

Browse source

RISC-V can use the information from PT_FEAT_DETAILED_GATHER to
compute the best stride to generate the single TLB invalidations.

Pass the gather down to the lower functions and create a full-range
gather for the flush-all callback.
