This updates Linux kernel for Synopsys ARC HS38 VDK so it matches real
platform and while at it bump kernel version to the latest.
Main changes:
* Linux kernel v4.9.6 (latest in 4.9.x series in buildroot)
* Add support of MMC controller which is used for rootfs
* Add support of UIO which is used to communicate with EVSS
Now with this update image built by vanilla Buildroot VDK has
working UART, MMC, LCD, Ethernet, UIO etc.
And while at it we rename defconfing so it:
1) Doesn't mention SMP any more - that's the only option anyways now
2) Matches common naming scheme: vendor_arch_platform
