--------------------------------
[ Upstream commit 9be013b2a9ecb29b5168e4b9db0e48ed53acf37c ]
Commit 0e00a8c9fd92 ("powerpc: Allow CPU selection also on PPC32") enlarged the CPU selection logic to PPC32 by removing depend to PPC64, and failed to restrict that depend to E5500_CPU and E6500_CPU. Fortunately that got unnoticed because -mcpu=8540 will override the -mcpu=e500mc64 or -mpcu=e6500 as they are ealier, but that's fragile and may no be right in the future.
Add back the depend PPC64 on E5500_CPU and E6500_CPU.
