hal::spi_multi_profile converter

[kammce]

This SPI implementation generates additional SPI driver objects. Each of these keeps a pointer to the original SPI driver and keeps a copy of their configuration. Any time any one of those SPI peripherals is used, it will reconfigure the SPI according to its configuration and will then perform the transaction. This provides a means for SPI peripheral drivers to be used with different drivers using SPI and allows them to have different speeds between each other versus having a singular speed for all.
