[v1,5/7] DCE/DSE: riscv: move syscall tables to syscalls/

Commit Message

Zhangjin Wu Sept. 25, 2023, 10:41 p.m. UTC

Both syscall table and compat syscall table share some dead syscalls
elimination code, to avoid cluttering the main RISC-V kernel Makefile,
let's move these tables and the corresponding compile settings to
syscalls/.
