efi_loader: ACPI tables must be in EfiACPIReclaimMemory
The UEFI spec does not allow ACPI tables to be in runtime services memory.
It recommends EfiACPIReclaimMemory.
Remove a superfluous check that the allocated pages are 16 byte aligned.
EFI pages are 4 KiB aligned.
Fixes: 86df34d42b05 ("efi_loader: Install ACPI configuration tables")
