Add STM32F7 SPI support

Browse source

Merge series from Ben Wolsieffer <ben.wolsieffer@hefring.com>:

This series adds support for SPI on STM32F7 processors. The STM32F7 SPI
peripheral is nearly identical to the STM32F4, with the only significant
differences being that it supports a wider range of word sizes, and the
addition of 32-bit transmit and receive FIFOs.
