Revert "arm64: account for sparsemem section alignment when choosing vmemmap offset"
This reverts commit 36e5cd6b897e17d03008f81e075625d8e43e52d0, since the section alignment is now guaranteed by construction when choosing the value of memstart_addr. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Will Deacon <will.deacon@arm.com>
