powerpc: Fix missing declaration of [en/dis]able_kernel_altivec()
When CONFIG_PPC64 is set and CONFIG_ALTIVEC is not the following build failures occur: drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/dc_fpu.c: In function 'dc_fpu_begin': >> drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/dc_fpu.c:61:17: error: implicit declaration of function 'enable_kernel_altivec'; did you mean 'enable_kernel_vsx'? [-Werror=implicit-function-declaration] 61 | enable_kernel_altivec(); | ^~~~~~~~~~~~~~~~~~~~~ | enable_kernel_vsx drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/dc_fpu.c: In function 'dc_fpu_end': >> drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/dc_fpu.c:89:17: error: implicit declaration of function 'disable_kernel_altivec'; did you mean 'disable_kernel_vsx'? [-Werror=implicit-function-declaration] 89 | disable_kernel_altivec(); | ^~~~~~~~~~~~~~~~~~~~~~ | disable_kernel_vsx cc1: some warnings being treated as errors This commit adds stub instances of both enable_kernel_altivec() and disable_kernel_altivec() the same way as done in commit bd73758803c2 regarding enable_kernel_vsx() and disable_kernel_vsx().
