fix(errata): check for SCU before accessing DSU
The DSU contains system control registers in the SCU and L3 logic to
control the functionality of the cluster. If "DIRECT CONNECT" L3 memory
system variant is used, there won't be any L3 cache, snoop filter, and
SCU logic present hence no system control register will be present.
Hence check SCU presence before accessing DSU register for DSU_2313941
errata.
