fix nasty bug in ISR handler, where interrupt was not properly acknowleged (write to CR instead of ISR, as intended). Also, minor, set the LSI prescaler values more appropriately (though not critical since LSI is so low precision anyway).

correct the RTC_ALRMR_ENABLE value, it needs to ignore the date/dow component since that is not set. Also, the prescaler value for HSE (which presumes 1 MHz, anyway) had transposed digits.

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.
