This is the 2nd PR in a series of PR to support the STM32L4 series in micropython. (see http://forum.micropython.org/viewtopic.php?f=12&t=1332&sid=64e2f63af49643c3edee159171f4a365)
I add the hal files from STM32Cube_FW_L4_V1.3.0 with windows line ending converted to unix. Only basic hal files are added. In addition the QSPI support is included to support later the QSPI flash as mass storage.
