dm: acpi: Enhance acpi_get_name()
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.
