QEMU provides SMBIOS tables with detailed information. We should not try to
replicate them in U-Boot.

If we want to inform about U-Boot, we can add a Firmware Inventory
Information (type 45) table in future.

The smbios.h include does not use any definitions from ofnode.h.
So don't include it.

As DECLARE_GLOBAL_DATA_PTR is no longer defined via dm/of.h we need to
add it to efi_smbios.c.

Add now missing includes to smbios-parser.c.

Remove a superfluous check comparing the sizes of the SMBIOS 2.1 and SMBIOS
3.0 anchors.

At present this code allocates memory when writing the tables and
then unnecessarily adds another memory map when installing it.

Adjust the code to allocate the tables using the normal U-Boot
mechanism. This avoids doing an EFI memory allocation early in
U-Boot, which may use memory that would be overwritten by a
'load' command, for example.

Only the v3 table is supported now, so always use this when installing
the EFI table.

EFI does not use the 'anchor string' to determine the SMBIOS table
version, instead preferring to have two separate GUIDs. Use the correct
one, depending on the table version.

Call unmap_system() to balance to the use of map_sysmem()

This should access arch-specific properties. Fix it and update the

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>.

We currently use an outdated format 32-bit format for SMBIOS tables.
So we must allocate SMBIOS tables below 4 GiB.

U-Boot should set up the SMBIOS tables during startup, as it does on x86.
Ensure that it does this correctly on non-x86 machines too, by creating
an event spy for last-stage init.

Tidy up the installation-condition code while we are here.
