ppc: qemu: Create a virtual memory mapping of the platform bus

Browse Source 
QEMU ppce500 target can dynamically instantiate an eTSEC device on
a platform bus if "-device eTSEC" is given to QEMU. It is presented
as a "simple-bus" in the device tree, with an additional compatible
string "qemu,platform".

Let's create a virtual memory mapping for it in misc_init_r(), in
preparation to adding eTSEC support.
