* stm32f429i-disco: Fixes eliminated register control by compiler optimization
When reading 1 byte from the SPI device the clock must be enabled and
immediately disabled. This section has been optimized by the compiler (-O2) to a
missing active spi clock. A subsequently block read failed because of missing
response from the spi device. This has been lead to a broken display
initializing.
