EFI: Allocate EFI boot related struct from EFI allocation pool

Browse Source 
Current EFI boot related structs are allocated right after HV binary, and
marked as EfiResered. In fact, the memory should be reclaimed and
managed by HV once EFI boot is done, Moreover, HV is doing 2M alignment,
which is overwriting this allocated memory. This patch is to allocate EFI
info from EFI allocation pool and marked as EFiloaderdata, so that the
memory is used by HV, also, it will reduce the fragmentation.
