bus/fslmc: change EQCR stashing threshold to 1

Browse Source 
Changing the EQCR stashing threshold boosts the performance
of l3fwd application on LS2088 by more than 20% as it helps
in burst packet processing at the Tx side. CPU is immediately
informed about the empty EQCR entries once consumed by the
hardware.
