[PATCH] powerpc/embedded6xx: select MPC10X_BRIDGE only if PCI is set

When CONFIG_SMP is not set, CONFIG_BROKEN_ON_SMP is set, and
CONFIG_PCI is not set, there can be a kconfig warning:

WARNING: unmet direct dependencies detected for PPC_INDIRECT_PCI
  Depends on [n]: PCI [=n]
  Selected by [y]:
  - MPC10X_BRIDGE [=y]

To fix that, make the selects of MPC10X_BRIDGE be conditional
on PCI.

That would work, but using "imply" would be preferable as it doesn't
have to encode anything about the PCI dependency.
