dm: sandbox: Add a SPI emulation uclass
U-Boot includes a SPI emulation driver already but it is not explicit, and is hidden in the SPI flash code.
Conceptually with sandbox's SPI implementation we have a layer which creates SPI bus transitions and a layer which interprets them, currently only for SPI flash. The latter is actually an emulation, and it should be possible to add more than one emulation - not just SPI flash.
Add a SPI emulation uclass so that other emulations can be plugged in to support different types of emulated devices on difference buses/chip selects.
