85xx: Fix relocation of CCSRBAR
If the virtual address for CCSRBAR is the same after relocation but
the physical address is changing we'd end up having two TLB entries with
the same VA. Instead we new us the new CCSRBAR virt address + 4k as a
temp virt address to access the old CCSRBAR to relocate it.
