mb/intel/kblrvp: Enable Kabylake RVP8

Add support for KBL RVP8 board

* Add KBL RVP8 support in Konfig.
* Add KBL RVP8 config option in make menuconfig.
* Add descriptor and ME binary paths for RVP8 in Kconfig.
* Add RVP8 board name Kconfig.name.
* Add devicetree.cb for RVP8 in the variants path.
* Add gpio.h for RVP8 in variants/include/variant path.

TEST= Build and boot RVP8.
