trusty: implement hypercall to initialize trusty

Browse Source 
UOS_Loader will trigger boot of Trusty-OS by HC_INITIALIZE_TRUSTY.
UOS_Loader will load trusty image and alloc runtime memory for
trusty. UOS_Loader will transfer these information include
trusty runtime memory base address, entry address and memory
size to hypervisor by trusty_boot_param structure.

In hypervisor, once HC_INITIALIZE_TRUSTY received, it will create
EPT for Secure World, save Normal World vCPU context, init
Secure World vCPU context and switch World state to Secure World.
