Divide the monolithic SBI FWFT (Firmware Features) register list into separate sublists, each testing a specific FWFT feature independently with proper dependency checking. Previously, all FWFT features were tested together in a single sublist. This caused issues because: 1. Not all FWFT features are available on all platforms 2. Some features depend on specific ISA extensions (e.g., pointer_masking requires Smnpm) 3. Tests would fail if any single feature was unavailable Add the feature-specific SBI FWFT sublists with the following improvements: - Add check_fwft_feature() helper to verify FWFT feature availability at runtime - Update filter_reg() to handle per-feature FWFT register filtering Signed-off-by: Yong-Xuan Wang <yongxuan.wang@sifive.com> Reviewed-by: Anup Patel <anup@brainfault.org> Link: https://lore.kernel.org/r/20260601-kvm-get_reg_list-v2-v5-5-415d08a2813b@sifive.com Signed-off-by: Anup Patel <anup@brainfault.org>
