acpi: Add an acpi command
It is useful to dump ACPI tables in U-Boot to see what has been generated. Add a command to handle this. To allow the command to find the tables, add a position into the global data. Support subcommands to list and dump the tables. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Wolfgang Wallner <wolfgang.wallner@br-automation.com>
