This patch switches kernel version to 5.4 for archs38.

Changes since v1:
1) Remove disabling of ath9k-htc package usage.
   On initial port in config-5.4 file the option
   "CONFIG_USB_SUPPORT" was missing what caused 
   build failure.
2) Instead of switching to GCC9 introduce Linux kernel
  patch which adds compiler option to workaround ICE


Evgeniy Didin (4):
  archs38: add kernel 5.4 config
  archs38: Add patch for gcc8 compilance
  archs38: switch to kernel 5.4 by default
  kernel: update arc-specific patch

Hi Evgeniy,

I applied your patches with some minor changes to the config patch:
https://git.openwrt.org/?p=openwrt/openwrt.git;a=commitdiff;h=e3bcb837209af464e862813f514f76f3b6315124
Please check if it is really working.

Will you also provide an update to kernel 5.4 for the arc770 target?

Are you trying to get a fix or workaround for the problem with GCC 8.4.0
into the mainline kernel or GCC 8.X?
