After the patch to restrict the use of mmap() to CAP_SYS_RAWIO for
the currently existing devices, most applications can no longer make
use of the accelerators as in production "you don't run things as root".

To keep the DSA and IAA accelerators usable, hook up a write() method
so that applications can still submit work. In the write method,
sufficient input validation is performed to avoid the security issue
that required the mmap CAP_SYS_RAWIO check.

One complication is that the DSA device allows for indirect ("batched")
descriptors. There is no reasonable way to do the input validation
on these indirect descriptors so the write() method will not allow these
to be submitted to the hardware on affected hardware, and the sysfs
enumeration of support for the opcode is also removed.

Early performance data shows that the performance delta for most common
cases is within the noise.

On Sapphire Rapids and related platforms, the DSA and IAA devices have an
erratum that causes direct access (for example, by using the ENQCMD or
MOVDIR64 instructions) from untrusted applications to be a security problem.

To solve this, add a flag to the PCI device enumeration and device structures
to indicate the presence/absence of this security exposure. In the mmap()
method of the device, this flag is then used to enforce that the user
has the CAP_SYS_RAWIO capability.

In a future patch, a write() based method will be added that allows untrusted
applications submit work to the accelerator, where the kernel can do
sanity checking on the user input to ensure secure operation of the accelerator.

Due to an erratum with the SPR_DSA and SPR_IAX devices, it is not secure to assign
these devices to virtual machines. Add the PCI IDs of these devices to the VFIO
denylist to ensure that this is handled appropriately by the VFIO subsystem.

The SPR_DSA and SPR_IAX devices are on-SOC devices for the Sapphire Rapids
(and related) family of products that perform data movement and compression.

file_ida is allocated during cdev open and is freed accordingly
during cdev release. This sequence is guaranteed by driver file
operations. Therefore, there is no need to destroy an already empty
file_ida when the WQ cdev is removed.

Worse, ida_free() in cdev release may happen after destruction of
file_ida per WQ cdev. This can lead to accessing an id in file_ida
after it has been destroyed, resulting in a kernel panic.

Remove ida_destroy(&file_ida) to address these issues.
