The parse_satp_mode function is used to parse SATP. Use SATP (Supervised Address Translation and Protection) mode at JVM startup and explicitly warn and stop early when sv57 is enabled [1]. Tier1 tested with fastdebug build using qemu systems. This is a risc-v specific change. Backport is clean, risk is low.
