STM32F2/F4: SPI fixes.

Browse Source 
- Rename SPI_CR2_FRF_TI to SPI_CR2_FRF_TI_MODE to match datasheet.

 - Rename SPI_CR2_FRF_MOTOROLA to SPI_CR2_FRF_MOTOROLA_MODE (see above).

 - Fix SPI_CR2_FRF_MOTOROLA_MODE bit definition, must be (0 << 4).

 - Change SPI_SR_RXNE to SPI_SR_TIFRFE; this was probably a copy-paste
   error. Also, the bit definition is (1 << 8).
