[PATCH -next?] powerpc/fsl_uli1575: fix kconfig warnings and build errors

[Randy Dunlap]

Neither FSL_SOC_BOOKE nor PPC_86xx enables CONFIG_PCI by
default, so it may be unset in some randconfigs.
When that happens, FSL_ULI1575 may be set when it should not be
since it is a PCI driver. When it is set, there are 3 kconfig
warnings and a slew of build errors

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

WARNING: unmet direct dependencies detected for GENERIC_ISA_DMA
  Depends on [n]: ISA_DMA_API [=n]
  Selected by [y]:
  - FSL_ULI1575 [=y] && (FSL_SOC_BOOKE [=n] || PPC_86xx [=y])

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

and 30+ build errors.
