Add an eager_page_split module parameter for RISC-V KVM, following the same approach as on x86. This parameter controls whether eager page splitting is enabled. The default value is on. When eager page splitting is enabled, KVM proactively splits large pages (huge pages) into smaller pages when needed for dirty logging or other operations. Disabling it can be beneficial for VM workloads that rarely perform writes, or that only write to a small region of memory, as it allows huge pages to remain intact for read accesses.
