SPI speed fast PLL clock

Hello,
I am currently trying to get my SPI bus to operate at the datasheet listed 48MHz. My understanding is all I need to do is set up my initial clocks with the 96MHz PLL and then in the platform_devices.h just set my divider to the minimum (2). Unfortunately I can't seem to get my spi clock to run faster than 8MHz, which leads me to believe that the clock set up is not changing from 16MHz.

Here is the relevant code:
