include/hw/ide/internal.h is currently included by include/hw/ide/pci.h
and thus exposed to a lot of files that are not part of the IDE subsystem.
Stop including internal.h there and use the appropriate new headers
ide-bus.h and ide-dma.h instead.

For distros like downstream RHEL, it would be helpful to allow to disable
the CompactFlash device. For making this possible, we need a separate
Kconfig switch for this device, and the code should reside in a separate
file. Let's also introduce a new header ide-dev.h which can be used to
collect definitions related to IDE devices.

Allow the VIA IDE controller to switch between both legacy and native modes by
calling pci_ide_update_mode() to reconfigure the device whenever PCI_CLASS_PROG
is updated.
This patch moves the initial setting of PCI_CLASS_PROG from via_ide_realize() to
via_ide_reset(), and removes the direct setting of PCI_INTERRUPT_PIN during PCI
bus reset since this is now managed by pci_ide_update_mode(). This ensures that
the device configuration is always consistent with respect to the currently
selected mode.

The via-ide device currently attempts to set the default BAR addresses to the
values shown in the datasheet, but this doesn't work for 2 reasons: firstly
BARS 1-4 do not set the bottom 2 bits to PCI_BASE_ADDRESS_SPACE_IO, and
secondly the initial PCI bus reset clears the values of all PCI device BARs
after the device itself has been reset.
Remove the setting of the default BAR addresses from via_ide_reset() to ensure
there is no doubt that these values are never exposed to the guest.

This function reads the value of the PCI_CLASS_PROG register for PCI IDE
controllers and configures the PCI BARs and/or IDE ioports accordingly.
In the case where we switch to legacy mode, the PCI BARs are set to return zero
(as suggested in the "PCI IDE Controller" specification), the legacy IDE ioports
are enabled, and the PCI interrupt pin cleared to indicate legacy IRQ routing.
Conversely when we switch to native mode, the legacy IDE ioports are disabled
and the PCI interrupt pin set to indicate native IRQ routing. The contents of
the PCI BARs are unspecified, but this is not an issue since if a PCI IDE
controller has been switched to native mode then its BARs will need to be
programmed.

Legacy software contains a standard mechanism for generating a reset to a
Serial ATA device - setting the SRST (software reset) bit in the Device
Control register.
Serial ATA has a more robust mechanism called COMRESET, also referred to
as port reset. A port reset is the preferred mechanism for error
recovery and should be used in place of software reset.
Commit e2a5d9b3d9 ("hw/ide/ahci: simplify and document PxCI handling")
improved the handling of PxCI, such that PxCI gets cleared after handling
a non-NCQ, or NCQ command (instead of incorrectly clearing PxCI after
receiving anything - even a FIS that failed to parse, which should NOT
clear PxCI, so that you can see which command slot that caused an error).
However, simply clearing PxCI after a non-NCQ, or NCQ command, is not
enough, we also need to clear PxCI when receiving a SRST in the Device
Control register.
A legacy software reset is performed by the host sending two H2D FISes,
the first H2D FIS asserts SRST, and the second H2D FIS deasserts SRST.
The first H2D FIS will not get a D2H reply, and requires the FIS to have
the C bit set to one, such that the HBA itself will clear the bit in PxCI.
The second H2D FIS will get a D2H reply once the diagnostic is completed.
The clearing of the bit in PxCI for this command should ideally be done
in ahci_init_d2h() (if it was a legacy software reset that caused the
reset (a COMRESET does not use a command slot)). However, since the reset
value for PxCI is 0, modify ahci_reset_port() to actually clear PxCI to 0,
that way we can avoid complex logic in ahci_init_d2h().
This fixes an issue for FreeBSD where the device would fail to reset.
The problem was not noticed in Linux, because Linux uses a COMRESET
instead of a legacy software reset by default.
