powerpc: Remove some unused functions
Remove slice_set_psize() which is not used. It was added in 3a8247cc2c85 "powerpc: Only demote individual slices rather than whole process" but was never used. Remove vsx_assist_exception() which is not used. It was added in ce48b2100785 "powerpc: Add VSX context save/restore, ptrace and signal support" but was never used. Remove generic_mach_cpu_die() which is not used. Its last caller was removed in 375f561a4131 "powerpc/powernv: Always go into nap mode when CPU is offline". Remove mpc7448_hpc2_power_off() and mpc7448_hpc2_halt() which are unused. These were introduced in c5d56332fd6c "[POWERPC] Add general support for mpc7448hpc2 (Taiga) platform" but were never used. This was partially found by using a static code analysis program called cppcheck.
