powerpc/85xx: Adding configuration for DCSRCR to enable 32M access
Configuring DCSRCR to define the DCSR space to be 1G instead
of the default 4M. DCSRCR only allows selection of either 4M
or 1G.
Most DCSR registers are within 4M but the Nexus trace buffer
is located at offset 16M within the DCSR.
Configuring the LAW to be 32M to allow access to the Nexus
trace buffer. No TLB modification is required since accessing
the Nexus trace buffer from within u-boot is not required.
