The service parsing logic is used to parse the configuration string provided by the user using the attribute qat/cfg_services in sysfs. The logic relies on hard-coded strings. For example, the service "sym;asym" is also replicated as "asym;sym". This makes the addition of new services or service combinations complex as it requires the addition of new hard-coded strings for all possible combinations. This commit addresses this issue by: * reducing the number of internal service strings to only the basic service representations. * modifying the service parsing logic to analyze the service string token by token instead of comparing a whole string with patterns. * introducing the concept of a service mask where each service is represented by a single bit. * dividing the parsing logic into several functions to allow for code reuse (e.g. by sysfs-related functions). * introducing a new, device generation-specific function to verify whether the requested service combination is supported by the currently used device.
