Victor Sun 16624bab5e HV: modularization: use loader_name char array in acrn boot info
The patch has below changes:
	1. rename mi_loader_name in acrn_boot_info struct to loader_name;
	2. change loader_name type from pointer to array to avoid accessing
	   original multiboot info region;
	3. remove mi_drivers_length and mi_drivers_addr which are never used;

Tracked-On: #5661
