[PATCH 4/5] riscv: kvm: Use SYM_*() assembly macros instead of deprecated ones

[Clément Léger]

ENTRY()/END()/WEAK() macros are deprecated and we should make use of the
new SYM_*() macros [1] for better annotation of symbols. Replace the
deprecated ones with the new ones and fix wrong usage of END()/ENDPROC()
to correctly describe the symbols.
