[Buildroot] [PATCH] configs/csky_gx6605s: bump kernel to 5.0 and use buildroot toolchain

[guoren at kernel.org <guoren@kernel.org>]

From: Guo Ren <ren_guo@c-sky.com>

The most thing is to use the toolchain compiled by buildroot itself. And
we also bump kernel to 5.0 with kernel.org.

For all 610s including qemu we use 0x10000000 PHYS_OFFSET for unified
maintain. There is no gx6605s.dts for the config, so we need wget it from
csky gitlab CI storage.
