This patch fixes error in the setting of the hw statistics module base for K2HK platform. In K2HK although there are 4 hw statistics modules, but only 2 are visible at a time. Thus when setting up the pointers to the base of the corresponding hw statistics modules, modules 0 and 2 should point to one base, while modules 1 and 3 should point to the other.
