board/lego/ev3: update to 4.14 kernel and 2017.11 U-Boot
This updates the LEGO MINDSTORMS EV3 board to Linux kernel 4.14 and U-Boot 2017.11. * Kernel patches are dropped because they are in mainline now. * This caused the kernel image to be >3M so some adjustments to the image sizes/layout needed to be made in U-Boot. * Updated U-Boot version bumped since we are touching this config anyway Signed-off-by: David Lechner <david@lechnology.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

-Subject: ARM: da850-lego-ev3: Add device tree node for sound
-
-This adds a device tree node for sound on LEGO MINDSTORMS EV3. The EV3
-uses one of the SoC PWMs connected to an amplifier to create sound from
-a speaker.
-
-The PWM is passed through a low-pass filter, so it is actually possible
-to do PCM playback, but there is no existing driver, so just using
-pwm-beeper for now, since it is also a compatible mode of operation.

+Subject: [PATCH] configs: legoev3: increase flash image sizes
+
+This increases the kernel image to 4M and the rootfs image to 10M.
+
+It is getting hard to get a kernel image to fit in 3M and the rootfs image
+size now matches the filesyssize variable.
