This code uses FP (floating point), Altivec and VSX (Vector-Scalar
Extension). It can just depend on CONFIG_VSX though, because that
already depends on FP and Altivec.
Otherwise we get lots of link errors such as:
drivers/built-in.o: In function `.p8_aes_setkey':
aes.c:(.text+0x2d325c): undefined reference to `.enable_kernel_altivec'
aes.c:(.text+0x2d326c): undefined reference to `.enable_kernel_vsx'
