To identify if the instruction has any memory reference,
"memory_ref_char" field needs to be set for specific architecture.
Example memory instruction:
lwz     r10,0(r9)

Here "(" is the memory_ref_char. Set this as part of arch->objdump

To get register number and access offset from the given instruction,
arch->objdump.register_char is used. In case of powerpc, the register
char is "r" (since reg names are r0 to r31). Hence set register_char
as "r".
