/**
* Marlin currently requires 3 SPI classes:
*
* SPIClass:
* This class is normally provided by frameworks and has a semi-default interface.
* This is needed because some libraries reference it globally.
*
* SPISettings:
* Container for SPI configs for SPIClass. As above, libraries may reference it globally.
*
* These two classes are often provided by frameworks so we cannot extend them to add
* useful methods for Marlin.
*
* MarlinSPI:
* Provides the default SPIClass interface plus some Marlin goodies such as a simplified
* interface for SPI DMA transfer.
