The message "EFI using ACPI tables at %lx\n" is only of interest when
debugging. Make it a debug message.

We largely do not need <common.h> in these files, so drop it. The only
exception here is that efi_freestanding.c needs <linux/types.h> and had
been getting that via <common.h>.

U-Boot sets up the ACPI tables during startup. Rather than creating a
new set, install the existing ones. Create a memory-map record to cover
the tables.

The current EFI implementation confuses pointers and addresses. Normally
we can get away with this but in the case of sandbox it causes failures.
Despite the fact that efi_allocate_pages() returns a u64, it is actually
a pointer, not an address. Add special handling to avoid a crash when
running 'bootefi hello'.

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.

This file is potentially useful to other architectures saddled with ACPI
so move most of its contents to a common location.

ACPI tables can be passed via EFI configuration table to an EFI
application. This is only supported on x86 so far.
