Add a new method to acpi_ops to let drivers fill out ACPI MADT.
The code is unused for now until drivers implement the new ops.
TEST: Booted on QEMU sbsa using driver model generated MADT.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.
This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

acpi_add_other_item() passes dev = NULL. Instead of dev->name write the
string "other" to the debug log:

At present this is really just a debugging aid, but it is a bit untidy.
Add proper columns and display the type name instead of a number.

At present this list is used to collect items within the DSDT and SSDT
tables. It is useful for it to collect the whole tables as well, so there
is a list of what was created and which write created each one.
Refactor the code accordingly.

The Intel Non-High-Definition-Audio Link Table (NHLT) table describes the
audio codecs and connections in a system. Various devices can contribute
information to produce the table.
Add core support for this, based on a structure which is built up through
calls to the driver.

For many device types it is possible to figure out the name just by
looking at its uclass or parent. Add a function to handle this, since it
allows us to cover the vast majority of cases automatically.
However it is sometimes impossible to figure out an ACPI name for a device
just by looking at its uclass. For example a touch device may have a
vendor-specific name. Add a new "acpi,name" property to allow a custom
name to be created.
With this new feature we can drop the get_name() methods in the sandbox
I2C and SPI drivers. They were only added for testing purposes. Update the
tests to use the new values.

ACPI (Advanced Configuration and Power Interface) is a standard for
specifying information about a platform. It is a little like device
tree but the bindings are part of the specification and it supports an
interpreted bytecode language.
Driver model does not use ACPI for U-Boot's configuration, but it is
convenient to have it support generation of ACPI tables for passing to
Linux, etc.
As a starting point, add an optional set of ACPI operations to each
device. Initially only a single operation is available, to obtain the
ACPI name for the device. More operations are added later.
Enable ACPI for sandbox to ensure build coverage and so that we can add
tests.
