hexagon: traps: remove sys_syscall()

Clang warns:

  arch/hexagon/kernel/traps.c:335:6: warning: no previous prototype for function 'sys_syscall' [-Wmissing-prototypes]
    335 | long sys_syscall(void)
        |      ^
  arch/hexagon/kernel/traps.c:335:1: note: declare 'static' if the function is not intended to be used outside of this translation unit
    335 | long sys_syscall(void)
        | ^
        | static

This function is not used anywhere, so remove it.
