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.
