Set WARNS if not set for EFI boot code and fix the issues highlighted by setting it. Most components are set to WARNS level 6 with few being left at lower levels due to the amount of changes needed to fix at higher levels. Error types fixed: * Missing / invalid casts * Missing inner structs * Unused vars * Missing static for internal only funcs * Missing prototypes * Alignment changes * Use of uninitialised vars * Unknown pragma (intrinsic) * Missing types etc due to missing includes * printf formatting types Reviewed by: emaste (in part) MFC after: 2 weeks X-MFC-With: r293268 Sponsored by: Multiplay Differential Revision: https://reviews.freebsd.org/D4839
