env->psa is a 64bit value, while we copy 4 bytes into the save area,
resulting always in 0 getting stored.
Let's try to reduce such errors by using a proper structure. While at
it, use correct cpu->be conversion (and get_psw_mask()), as we will be
reusing this code for TCG soon.

Replace direct access which implicitly assumes no IDA
or MIDA with the new ccw data stream interface which should
cope with these transparently in the future.

This is a preparation for introducing handling for indirect data
addressing and modified indirect data addressing (CCW). Here we introduce
an interface which should make the addressing scheme transparent for the
client code. Here we implement only the basic scheme (no IDA or MIDA).

Let's add indirect data addressing support for our virtual channel
subsystem. This implementation does not bother with any kind of
prefetching. We simply step through the IDAL on demand.

The architecture mandates the addresses to be accessed on the first
indirection level (that is, the data addresses without IDA, and the
(M)IDAW addresses with (M)IDA) to be checked against an CCW format

Abstract
The objective of this series is introducing CCW IDA (indirect data
access) support to our virtual channel subsystem implementation. Briefly
CCW IDA can be thought of as a kind of a scatter gather support for a
single CCW. If certain flags are set, the cda is to be interpreted as
