crypto: qat - add get_svc_slice_cnt() in device data structure 



Enhance the adf_hw_device_data structure by introducing a new callback
function get_svc_slice_cnt(), which provides a mechanism to query the
total number of accelerator available on the device for a specific
service.

Implement adf_gen4_get_svc_slice_cnt() for QAT GEN4 devices to support this
new interface. This function returns the total accelerator count for a
specific service.
