s390x/flic: make floating interrupts on TCG actually floating

Move floating interrupt handling into the flic. Floating interrupts
will now be considered by all CPUs, not just CPU #0. While at it, convert
I/O interrupts to use a list and make sure we properly consider I/O
sub-classes in s390_cpu_has_io_int().

s390x/flic: factor out injection of floating interrupts

Let the flic device handle it internally. This will allow us to later
on store floating interrupts in the flic for the TCG case.

This now also simplifies kvm.c. All that's left is the fallback
interface for floating interrupts, which is now triggered directly via
the flic in case anything goes wrong.

s390x/tcg: simplify machine check handling

We currently only support CRW machine checks. This is a preparation for
real floating interrupt support.

Get rid of the queue and handle it via the bit INTERRUPT_MCHK. We don't
rename it for now, as it will be soon gone (when moving crw machine checks
into the flic).

Please note that this is the same way also KVM handles it: only one
instance of a machine check can be pending at a time. So no need for a
queue.

While at it, make sure we try to deliver only if env->cregs[14]
actually indicates that CRWs are accepted.

Drop two unused defines on the way (we already have PSW_MASK_...).
