Rename (1) is_service_enabled() to adf_is_service_enabled(), and
(2) srv_to_cfg_svc_type() to adf_srv_to_cfg_svc_type(), and move them to
adf_cfg_services.c which is the appropriate place for configuration-related
service logic. This improves code organization and modularity by grouping
related service configuration logic in a single location.

The enums `adf_base_services` (used in rate limiting) and `adf_services`
define the same values, resulting in code duplication.
To improve consistency across the QAT driver: (1) rename `adf_services`
to `adf_base_services` in adf_cfg_services.c to better reflect its role
in defining core services (those with dedicated accelerators),
(2) introduce a new `adf_extended_services` enum starting from
`SVC_BASE_COUNT`, and move `SVC_DCC` into it, as it represents an
extended service (DC with chaining), and (3) remove the redundant
`adf_base_services` enum from the rate limiting implementation.
This does not introduce any functional change.

Add support to configure decompression as a separate service for QAT GEN6
devices. A new arbiter configuration has been added to map the hardware
decompression threads to all ring pairs.
The decompression service is enabled via sysfs by writing "decomp" to
"/sys/bus/pci/devices/<BDF>/qat/cfg_services".
The decompression service is not supported on QAT GEN2 and GEN4 devices,
and attempting it results in an invalid write error. The existing
compression service for QAT GEN2 and GEN4 devices remains unchanged and
supports both compression and decompression operations on the same ring
pair.

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 the function get_service_enabled() from adf_4xxx_hw_data.c to
adf_cfg_services.c and rename it as adf_get_service_enabled().
This function is not specific to the 4xxx and will be used by
other QAT drivers.
This does not introduce any functional change.

The file adf_cfg_services.h cannot be included in header files since it
instantiates the structure adf_cfg_services. Move that structure to its
own file and export the symbol.
