SPI: Document possibility of faster clock speeds #32

In brief

Details

In Adafruit_DotStar::hw_spi_init(), document the possibility of specifying faster hardware SPI clock speeds to provide faster LED updates at the risk of unreliable results.

The comment is placed after the __AVR_ATtiny85__ code as that does not appear to have a formal SPI interface. If the comment needs moved or adjusted, I'll gladly change it.

Skipping in-depth analysis as this is a documentation-only change.
