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.

Hypervisor does memory alignment during initializing paging(init_paging)
although the starting address allocated by EFI stub doesn't meet the
requirement. As a result, HV might overwrite some memory belong to UEFI
BIOS. The patch introduces a new routine to fix the issue.

2. they are saved when build for rootfs.

Now one macro is added to define the alignment requirement.
>#define __aligned(x) __attribute__((aligned(x)))
Some code uses the __aligned(x) to define the alignment while the other
code uses the original alignment definition.
So they are unified.
