Series [PULL,01/13] hw/ppc/sam460ex: Drop use of ppcuic_init() | expand

Commit Message

From: Peter Maydell <peter.maydell@linaro.org>

The function ppc405cr_init() has apparently been unused since it was
added in commit 8ecc7913525ecb in 2007.

Remove this dead code, so we don't have to convert it away from using
ppcuic_init().
