STM32: Moved SPI code into the common area.
Updated the documentation so that it appears in all families Also added it to the L1 area, but is untested. An addition to the memorymap allows commonality and a #ifdef added to the spi_common_all code to exclude the case of SPI3 for L1 and F0 as SPI3 doesn't exist in those. An rcc dispatch header was added to remove same code from the spi header.
