From: "Aneesh Kumar K.V" <aneesh.ku...@linux.vnet.ibm.com>
This switches early feature checks to use the non static key variant of
the function. In later patches we will be switching cpu_has_feature()
and mmu_has_feature() to use static keys and we can use them only after
static key/jump label is initialized. Any check for feature before jump
label init should be done using this new helper.
