Chaohong guo 9feab4cf29 HV: adjust the starting addr of HV to be 2M-aligned ...

In init_paging(), when modify page table, it does a round up to 2M on
the starting address of HV memory. If the address is not 2M aligned,
memory overwrite occurs, or memory attribute(cache, u/s) may be not
right. Besides, trusty memory (uos_sworld_memory) in .bss section is 2M
aligned during compiling,  after enabling HV memroy 2M alignment, when
relocation is enabled, EFI stub or other loaders just needs to find a
2M-aligned starting addr for HV memory.
