ath10k: enable encapsulation offload by default

Enable ath10k offload by default. This improves wireless performance
without requiring user configuration.
This adds ath10k_core to the AUTOLOAD section so that the frame_mode
paramter can be added to /etc/modules.d and passed to the driver.
The frame_mode 2 enables ethernet mode on the firmware/driver.
This parameter is set by passing a different value to the frame_mode
value on kmod insmod.
