Update request for SDHC default SPI Speed

[oguzhanbsolak]

Hi,

For the upcoming MAX78000FTHR facial recognition demo, we need a 25MHz SPI for SDHC to get a higher FPS.
Currently, this value is set to 10MHz at the SDHC/ff13/Source/diskio.c by the SPI_SPEED parameter. Is it possible to update the default value to 25MHz or add a new flag to enable high-speed spi usage for SDHC?

We can also support this. I'll add the ability to override the default SPI speed per-project.
