crypto: qat - configure arbiter mapping based on engines enabled
The hardware specific function adf_get_arbiter_mapping() modifies
the static array thrd_to_arb_map to disable mappings for AEs
that are disabled. This static array is used for each device
of the same type. If the ae mask is not identical for all devices
of the same type then the arbiter mapping returned by
adf_get_arbiter_mapping() may be wrong.
This patch fixes this problem by ensuring the static arbiter
mapping is unchanged and the device arbiter mapping is re-calculated
each time based on the static mapping.
