crypto: qat - consolidate services structure
[ Upstream commit 71713766380712c8ab2d604605e7b0b20f977801 ]
The data structure that associates a service id with its name is
replicated across the driver.
Remove duplication by moving this data structure to a new include file,
adf_cfg_services.h in order to have consistency across the drivers.
Note that the data structure is re-instantiated every time the new
include is added to a compilation unit.

crypto: qat - ignore subsequent state up commands
[ Upstream commit 9c20cb8b1847dedddec3d5163079290542bf00bf ]
If the device is already in the up state, a subsequent write of `up` to
the sysfs attribute /sys/bus/pci/devices/<BDF>/qat/state brings the
device down.
Fix this behaviour by ignoring subsequent `up` commands if the device is
already in the up state.

crypto: qat - fix state machines cleanup paths
[ Upstream commit c9ca9756f376f51f985130a0e599d956065d4c44 ]
Commit 1bdc85550a2b ("crypto: qat - fix concurrency issue when device
state changes") introduced the function adf_dev_down() which wraps the
functions adf_dev_stop() and adf_dev_shutdown().
In a subsequent change, the sequence adf_dev_stop() followed by
adf_dev_shutdown() was then replaced across the driver with just a call
to the function adf_dev_down().
The functions adf_dev_stop() and adf_dev_shutdown() are called in error
paths to stop the accelerator and free up resources and can be called
even if the counterparts adf_dev_init() and adf_dev_start() did not
complete successfully.
However, the implementation of adf_dev_down() prevents the stop/shutdown
sequence if the device is found already down.
For example, if adf_dev_init() fails, the device status is not set as
started and therefore a call to adf_dev_down() won't be calling
adf_dev_shutdown() to undo what adf_dev_init() did.
Do not check if a device is started in adf_dev_down() but do the
equivalent check in adf_sysfs.c when handling a DEV_DOWN command from
the user.

crypto: qat - expose pm_idle_enabled through sysfs
Expose 'pm_idle_enabled' sysfs attribute. This attribute controls how
idle conditions are handled. If it is set to 1 (idle support enabled)
when the device detects an idle condition, the driver will transition
the device to the 'MIN' power configuration.
In order to set the value of this attribute for a device, the device
must be in the 'down' state.
This only applies to qat_4xxx generation.

crypto: qat - extend configuration for 4xxx
A QAT GEN4 device can be currently configured for crypto (sym;asym) or
compression (dc).
This patch extends the configuration to support more variations of these
services, download the correct FW images on the device and report the
correct capabilities on the device based on the configured service.
The device can now be configured with the following services:
"sym", "asym", "dc", "sym;asym", "asym;sym", "sym;dc", "dc;sym",
"asym;dc", "dc;asym".
With this change, the configuration "sym", "asym", "sym;dc", "dc;sym",
"asym;dc", "dc;asym" will be accessible only via userspace, i.e. the driver
for those configurations will not register into the crypto framework.
Support for such configurations in kernel will be enabled in a later
patch.
The pairs "sym;asym" and "asym;sym" result in identical device config.
As do "sym;dc", "dc;sym", and "asym;dc", "dc;asym".
