crypto: qat - expose device config through sysfs for 4xxx
qat_4xxx devices can be configured to allow either crypto or compression
operations. At the moment, devices are configured statically according to
the following rule:
- odd numbered devices assigned to compression services
- even numbered devices assigned to crypto services
Expose the sysfs attribute /sys/bus/pci/devices/<BDF>/qat/cfg_services
to allow to detect the configuration of a device and to change it.
The `cfg_service` attribute is only exposed for qat_4xxx devices and it
is limited to two configurations: (1) "sym;asym" for crypto services and
"dc" for compression services.
