Code restructure in order to simplify class hierarchy
- remove S390SCLPDevice abstract base class
and move function pointers into new SCLPEventFacilityClass
- implement SCLPEventFacility as SysBusDevice
- use define constants for instance creation strings
The following ascii-art shows the class structure wrt the SCLP EventFacility
before (CURRENT) and after the restructure (NEW):
----

"s390-sclp-events-bus"

| SCLPEventsBus |

|BusState qbus |

This patch implements a floating-interrupt controller device (flic)
which interacts with the s390 flic kvm_device.

Add an sclp event for "cpu was hot plugged". This allows Qemu to deliver an
SCLP interrupt to the guest stating that the requested cpu hotplug was
completed.

Implement the CPU data in SCLP "Read SCP Info". And implement "Read CPU Info"
SCLP command. This data will be used by the guest to get information about hot
plugged cpus.

Add simple support for SCLP line-mode also known as operating
system messages. This can be added in addition to or instead of
the SCLP full screen console with -device sclplmconsole.

Move conversion tables to header file.
- In SCLP line mode processing EBCDIC/ASCII conversion is needed.
- An additional EBCDIC to ASCII conversion function is added.

Currently all handlers (quiesce, console) only handle one event type.
Some drivers will handle multiple (compatible) event types. Rework the
code accordingly.

Currently we announce interchanged receive/send masks. This did not
trigger a bug, since the sclp console has the same masks for
send/receive and the Linux guest does not check the sclp mask for simple
events like quiesce. With other event users like the sclp line mode
console, we will have different send/receive bits. Fix it.

Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches.
