crypto: qat - consolidate services structure

[ Upstream commit 71713766380712c8ab2d604605e7b0b20f977801 ]

The data structure that associates a service id with its name is
replicated across the driver.
Remove duplication by moving this data structure to a new include file,
adf_cfg_services.h in order to have consistency across the drivers.

Note that the data structure is re-instantiated every time the new
include is added to a compilation unit.
