mvebu: update kernel config

The config-3.10 doesn't specify the configuration of the backported PCI
features, and the Marvell EBU Device Bus Controller, this will prevent
a clean compile. This patch enables these features to archive a clean compile
without having to specify the state of these configuration after starting to
compile.
