Add a U suffix to avoid shifting into the sign bit (which is
undefined behaviour in C).

linux kernel 3.12 has changed intel-hda
driver to always check for FIFORDY, this
causes long hangs in guest since QEMU
always has this bit set to 0. We now simply set
it to 1 always, since we're synchronous anyway
and always ready to receive the stream

Fix position buffer updates to use the correct stream offset.
Without this patch both IN (record) and OUT (playback) streams
will update the IN buffer positions. The linux kernel notices
and complains:
hda-intel: Invalid position buffer, using LPIB read method instead.
The bug may also lead to glitches when recording and playing
at the same time:

pci_set_irq and the other pci irq wrappers use
PCI_INTERRUPT_PIN config register to compute device
INTx pin to assert/deassert.
An irq is allocated using pci_allocate_irq wrapper
only if is needed by non pci devices.
Removed irq related fields from state if not used anymore.

To be passed to object_initialize().
Since commit 39355c3826 the argument is
void*, so drop some superfluous (BusState *) casts or direct parent
field usages.

Switch the entire code base to using the new timer API.

The ich6 and ich9 variants either need to inherit one from the other,
or both from a common base class, otherwise its not possible to create
a QOM cast macro for use by the shared implementation functions.
Went for option B, with a common base class.
