For the moment, disable the built-in GPU kernel driver as there is a
mismatch between the driver version and the user-space GPU libraries.
Use the external module maintained by the community.

That commit disables CONFIG_FIRMWARE_IN_KERNEL which is needed by IMX
SDMA driver and maybe other drivers.
An example of functionality failing without that enabled is the audio
over HDMI.
While on it configure the atheros driver as module. Otherwise the kernel
tries to load the firmware from user-space before the rootfs being
mounted, giving error messages on boot:
ath6kl: No "atheros,board-id" property on wireless node.
ath6kl: Failed to get board file ath6k/AR6003/hw2.1.1/bdata.bin (-2), trying to find default board file.
ath6kl: Failed to get default board file ath6k/AR6003/hw2.1.1/bdata.SD31.bin: -2
ath6kl: Failed to init ath6kl core
ath6kl_sdio: probe of mmc3:0001:1 failed with error -2

Disable firmware loading from user-space (udev) as the kernel is able to
load the firmware directly.

Platform defconfig corresponds to sha1 'e1506ff' in the kernel.
At this point linux-3.10 continues to be the default, some device-tree
files were renamed and the external atheros module does not compile with
linux-3.14, so to use this kernel with dey-1.8, following lines are
needed in the project's local.conf:
PREFERRED_VERSION_linux-dey = "3.14"
KERNEL_DEVICETREE = " \

MACHINE_FEATURES_remove = "wifi"
