s390x/mmu: Implement ESOP-2 and access-exception-fetch/store-indication facility

We already implement ESOP-1. For ESOP-2, we only have to indicate all
protection exceptions properly. Due to EDAT-1, we already indicate DAT
exceptions properly. We don't trigger KCP/ALCP/IEP exceptions yet.

So all we have to do is set the TEID (TEC) to the right values
(bit 56, 60, 61) in case of LAP.

We don't have any side-effects (e.g., no guarded-storage facility),
therefore, bit 64 of the TEID (TEC) is always 0.

We always have to indicate whether it is a fetch or a store for all access
exceptions. This is only missing for LAP exceptions.
