mainboard/intel/glkrvp: Add support for GLKRVP

GLKRVP is a reference board for GLK SOC
RVP1 has DDR4 and RVP2 has LPDDR4
RVP2 is enabled by default and CONFIG_IS_GLK_RVP_1 should be selected
if building for RVP1

GLKRVP can work with internal Intel EC or external Chrome EC AIC.
For internal EC, CONFIG_EC_GOOGLE_CHROMEEC will not be selected (
CONFIG_GLK_INTEL_EC should be selected for internal EC config)

By default, CONFIG_GLK_CHROME_EC is selected for  external ChromeEC AIC
config.
