Add basic implementation of the AC'97 sound part used in VIA south
bridge chips. Not all features of the device is emulated, only one
playback channel is supported for now but this is enough to get sound
output from some guests using this device on pegasos2.

Back in the mists of time, before EISA came along and required per-pin
level control in the ELCR register, the i8259 had a single chip-wide
level-mode control in bit 3 of ICW1.
Even in the PIIX3 datasheet from 1996 this is documented as 'This bit is
disabled', but apparently MorphOS is using it in the version of the
i8259 which is in the Pegasos2 board as part of the VT8231 chipset.
It's easy enough to implement, and I think it's harmless enough to do so
unconditionally.

isa_get_irq() was added in commit 3a38d437ca
("Add isa_reserve_irq()" Fri Aug 14 11:36:15 2009) as:
a temporary interface to be used to allocate ISA IRQs for
devices which have not yet been converted to qdev, and for
special cases which are not suited for qdev conversions,
such as the 'ferr'.
We still use it 14 years later, using the global 'isabus'
singleton. In order to get rid of such *temporary* interface,
extract isa_bus_get_irq() which can take any ISABus* object.

While working on the Tulip driver i tried to write some Teledisk images to
a floppy image which didn't work. Turned out that Teledisk checks the written
data by issuing a READ command to the FDC but running the DMA controller
in VERIFY mode. As we ignored the DMA request in that case, the DMA transfer
never finished, and Teledisk reported an error.
The i8257 spec says about verify transfers:
3) DMA verify, which does not actually involve the transfer of data. When an
8257 channel is in the DMA verify mode, it will respond the same as described
for transfer operations, except that no memory or I/O read/write control signals
will be generated.
Hervé proposed to remove all the dma_mode_ok stuff from fdc to have a more
clear boundary between DMA and FDC, so this patch also does that.

Back in 2016, we discussed[1] rules for headers, and these were
generally liked:
1. Have a carefully curated header that's included everywhere first. We
got that already thanks to Peter: osdep.h.
2. Headers should normally include everything they need beyond osdep.h.
If exceptions are needed for some reason, they must be documented in
the header. If all that's needed from a header is typedefs, put
those into qemu/typedefs.h instead of including the header.
3. Cyclic inclusion is forbidden.
This patch gets include/ closer to obeying 2.
It's actually extracted from my "[RFC] Baby steps towards saner
headers" series[2], which demonstrates a possible path towards
checking 2 automatically. It passes the RFC test there.
