Clock has to be less than 100000Hz! This still needs refactoring Hence WIP

This code is a working example of SPI Master for the SAME70 on the SAME70 Xplained Ultra dev board.
Description (tell us what you changes or added or removed please)
Code for reference and experimentation only.
Tried getting SPI to work using the examples given in ATMEL start but didn't have any luck. The examples are all very complicated and lengthy. SAM has chip select peripherals NPCS0 through 3, and those examples all use NPCS0, however our dev boards do not expose the NPCS0 pin, so I believe that's where my issues stemmed from. I found an example project here which is more manual and simple. Made some modifications and managed to get something back from the MRAM on requesting the device ID.
How to test (if any tests done)
Just hooked up the pins to a logic analyzer and MRAM
