We plan to use jump label for cpu_has_feature. In order to implement
this we need to include the linux/jump_label_base.h in asm/cputable.h.
But it seems that asm/cputable.h is so basic header file for ppc that
it is almost included by all the other header files. The including of
the linux/jump_label_base.h will introduces various recursive inclusion.
And it is very hard to fix that. So we choose to move the function
cpu_has_feature to a separate header file before using the jump label
for it. No functional change.
