[Buildroot] [PATCH 4/4] imx6ulpico: Use kernel 4.8-rc5

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@nxp.com>

With kernel 4.8-rc5 we no longer need to use the "CONFIG_SMP=n" workaround
as the issue has been fixed upstream by commit 059e232089e4
("irqchip/gic: Allow self-SGIs for SMP on UP configurations")

We never make this version point to a Linux release candidate, we use
the latest stable version available.

This lacks the update to package/linux-headers/Config.in.host. I know
it's in PATCH 3/4, but PATCH 3/4 is not correct as it uses the kernel
headers from a release candidate as the default kernel headers, which
we never do.

However, we could merge the support for 4.8 kernel headers for those
who point to a custom kernel version, but for this, this patch should
gain some of the changes to package/linux-headers/Config.in.
