ppc: Remove deprecated ppcemb target

Browse Source 
There is no known available OS for ppc around anymore that uses page
sizes below 4k, so it does not make much sense that we keep wasting
our time on building and testing the ppcemb-softmmu target. It has
been deprecated since two releases, and nobody complained, so let's
remove this now.

@subsection Page size support < 4k for embedded PowerPC CPUs (since 2.12.0)
qemu-system-ppcemb will be removed. qemu-system-ppc (or qemu-system-ppc64)
should be used instead. That means that embedded 4xx PowerPC CPUs will not
support page sizes < 4096 any longer.
