Use TOOLCHAIN_VARIANT to indicate what XCC toolchain release
to use.
Set a reasonable default for the RG-2016.4 toolchain release.
D_108mini, D_212GP, D_233L are only in RF-2016.4, set that
appropriately.

* CONFIG_SOC is now properly set and we do not need a separate
XTENSA_CORE build variable
* Some unnecessary macro -D CFLAGS in the Xtensa Makefile removed
* There is no default SOC selection, it is now done explicitly in
the board's defconfig
* CONFIG_<board name> now renamed to CONFIG_SOC_<board name in
uppercase> to conform to established style.
