- NEW: Added a new setting to STM32 USBv1 allowing for some clock deviation
from 48MHz. Renamed setting USB_HOST_WAKEUP_DURATION to
STM32_USB_HOST_WAKEUP_DURATION for consistency.
- FIX: Fixed STM32 QSPI errata workaround (bug #1116).
- FIX: Fixed wrong condition in STM32 BDMAv1 driver (bug #1115).
- FIX: Fixed HSI48 not getting enabled on STM32H7 (bug #1114).
- FIX: Fixed LPUART1 support for STM32H7xx (bug #1113).
