HV: enable load zephyr kernel

Browse Source 
Zephyr kernel is stripped ram image, its entry and load address
are explicitly defined in vm configurations, hypervisor will load
Zephyr directly based on these configurations.

Currently we only support boot Zephyr from protected mode.

Tracked-On: #3214
