[ARM] Unuse another Linux PTE bit

L_PTE_ASID is not really required to be stored in every PTE, since we can identify it via the address passed to set_pte_at(). So, create set_pte_ext() which takes the address of the PTE to set, the Linux PTE value, and the additional CPU PTE bits which aren't encoded in the Linux PTE value.
