powerpc/64s: Fix allnoconfig build since uaccess flush

[ Upstream commit b6b79dd53082db11070b4368d85dd6699ff0b063 ]

Using DECLARE_STATIC_KEY_FALSE needs linux/jump_table.h.

Otherwise the build fails with eg:

  arch/powerpc/include/asm/book3s/64/kup-radix.h:66:1: warning: data definition has no type or storage class
     66 | DECLARE_STATIC_KEY_FALSE(uaccess_flush_key);

Fixes: 9a32a7e78bd0 ("powerpc/64s: flush L1D after user accesses")
