Sebastien Lorquet bef518095f Fix the STM32L4 SPI driver. That SPI driver is quite different. They now handle frames of arbitrary size between 4 and 16 bits. It was broken before a new bit has to be set (rx fifo threshold) to handle <= 8-bit transactions. If not set, the default is 16-bit packed >=8-bit frames and the RXNE bit is never set (it is set when 16-bits are received). weird things as always. ...

This also add 8-bit access routines to the data register, because a 16-bit access to the data register when the frame size is below 9 bits is interpreted as a packed dual frame exchange.
