The first entry of the ibm,drc-info property is an int encoded count of the number of drc-info entries that follow. The "value" pointer returned by of_prop_next_u32() is still pointing at the this value when we call of_read_drc_info_cell(). Fix up by incrementing the "value" pointer to point at the first element of the first drc-info entry prior.
