[PATCH 5.10 416/545] powerpc/32: Do not allow selection of e5500 or e6500 CPUs on PPC32

[ 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.
