SPI DMA based on teensy DmaSpi library
This is proof of concept, porting the teensy 3 DmaSpi library to mbed MK64F. Program does 8-bit DMA SPI transfers. Verified with jumper between MOSI and MISO and with logic analyzer. With SPI clock @12MHz, data rate for 1024 bytes is 10.6 mbs. With SPI clock @30MHz, 22.6 mbs
