CE layer is shared between pci and snoc target and results
in duplicate object inclusion if both modules are compiled
together statically and undefined KBUILD_MODNAME if
compiled as module.

Fix this by building ce layer in ath10k core module by
adding ce object inclusion with ATH10K_CE boolean CONFIG.

           This module adds support for wireless adapters based on
           Atheros IEEE 802.11ac family of chipsets.
 
           If you choose to build a module, it'll be called ath10k.
