[Buildroot] [PATCH] configs: freescale_imx31_3stack: bump kernel version to 4.1.15_2.0.0_ga

[Vincent Stehle]

From: Vincent Stehlé <vincent.stehle at laposte.net>

Switch to the kernel of release 4.1.15_2.0.0_ga, as it builds properly with
gcc 5.x, which is now the default.

We add a linux config fragment to disable the framebuffer, to repair the
build for imx_v6_v7_defconfig.

Hello Thomas and Fabio,

My friend Julien got the i.MX31 PDK and he could kindly test a few
buildroot configs!

His experiments show that mainline kernel will not boot "as is" on the PDK.
What he proposed instead is that we switch to a recent NXP/Freescale
release based on kernel 4.1, which does boot on the PDK.

Is that proposal fine with you, please?

Best regards,

Vincent.
