#     powerpc/crypto: Fix aes-gcm-p10 build when VSX=n
#     
#     When VSX is disabled, eg. microwatt_defconfig, the build fails with:
#     
#       In function ‘enable_kernel_vsx’,
#           inlined from ‘vsx_begin’ at arch/powerpc/crypto/aes-gcm-p10-glue.c:68:2,
#           inlined from ‘p10_aes_gcm_crypt.constprop’ at arch/powerpc/crypto/aes-gcm-p10-glue.c:244:2:
#       ...
#       arch/powerpc/include/asm/switch_to.h:86:9: note: in expansion of macro ‘BUILD_BUG’
#          86 |         BUILD_BUG();
#             |         ^~~~~~~~~
#     
#     Fix it by making the p10-aes-gcm code depend on VSX.
