riscv: remove log_debug() in enable_caches()

log_debug() cannot be used before log_init() has been called. Remove the
log_debug() statement in enable_caches() since it is called before
log_init() in initcall_run_r().

This fixes a bug where a RISC-V system which does not have the "zicbom"
extension (such as PIC64-HPSC/HX) would get lost in an infinite loop in
log_dispatch().
