[PATCH] ppc32: fix treeboot image entrypoint

Correctly specify treeboot based image entrypoint. Currently makefile 
uses $(ENTRYPOINT) which isn't defined anywhere. Each board port sets 
entrypoint-$(CONFIG_BOARD_NAME) instead.

Without this patch I cannot boot Ocotea (PPC440GX eval board) anymore. 
I was getting random "OS panic" errors from OpenBIOS for a while, but 
with current kernel I get them all the time (probably because image 
became bigger).

I wonder how that got lost when I think ENTRYPOINT was changed to
entrypoint-$(board_name).  Maybe we should also think about changing the
default entry point in mktreeboot.c, what do you think Eugene? or Matt?
