Description

Adjust function definitions in mp_cpudep.c.c to avoid clang 15 warnings

With clang 15, the following -Werror warnings are produced:

sys/powerpc/booke/mp_cpudep.c:54:20: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
cpudep_ap_bootstrap()
                   ^
                    void
sys/powerpc/booke/mp_cpudep.c:97:16: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
cpudep_ap_setup()
               ^
                void

This is because cpudep_ap_bootstrap() and cpudep_ap_setup() are declared
with (void) argument lists, but defined with empty argument lists. Make
the definitions match the declarations.
