[U-Boot] [PATCH 14/15] dm: spi: Clean up detection of sandbox SPI emulator

[sjg at google.com]

Now that we don't have to deal with the command-line flag we can simplify
the code for detecting the emulator. Remove the lookup based on the SPI
specification, relying just on the device tree to locate the emulator.
