riscv: mark some code and data as file-static
Several functions and arrays which are only used in the files in which they are declared are missing "static" qualifiers. Warnings for these symbols are reported by sparse: arch/riscv/kernel/vdso.c:28:18: warning: symbol 'vdso_data' was not declared. Should it be static? arch/riscv/mm/sifive_l2_cache.c:145:12: warning: symbol 'sifive_l2_init' was not declared. Should it be static? Resolve these warnings by marking them as static. This version incorporates feedback from Greentime Hu <greentime.hu@sifive.com>.
