The functions related to compression and crypto configurations were
previously declared static, restricting the visibility to the defining
source file. Remove the static qualifier, allowing it to be used in other
files as needed. This is necessary for sharing this configuration functions
with other QAT generations.

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.

Move logic that is common between QAT GEN4 accelerators to the
qat_common folder. This includes addresses of CSRs, setters and
configuration logic.
When moved, functions and defines have been renamed from 4XXX to GEN4.
Code specific to the device is moved to the file adf_gen4_hw_data.c.
Code related to configuration is moved to the newly created
adf_gen4_config.c.
This does not introduce any functional change.
