ArmPkg/BdsLib: Fixed cache cleaning in PreparePlatformHardware()
Because the D&I caches were clean before to be disabled, the cache
lines might have got dirty during the cache maintenance operations.
This fix disables D&I caches before to clean them. The performance
drops should be minimised as invalidating the I cache is only a
couple of instruction.
