Set I2C speed to 88kHz, use digital filter only and reworked idle clock recovery
The errata describes a possible problem in operation between 88kHz and 100kHz => Set speed as recommended as work around.
Based on reference implementation only one filter should be use. Choice was digital because only drawback is lag of wakeup functionality which is not used
I2C communication may be randomly interrupted e.g. by a RTE reset or firmware update => reworked recovery function to get I2C devices in idle state again (Clk and SDA HIGH)

/** ****************************************************************************** * @file stm32f4xx_ll_bus.h * @author MCD Application Team * @brief Header file of BUS LL module. @verbatim ##### RCC Limitations ##### ============================================================================== [..] A delay between an RCC peripheral clock enable and the effective peripheral enabling should be taken into account in order to manage the peripheral read/write from/to registers. (+) This delay depends on the peripheral mapping. (++) AHB & APB peripherals, 1 dummy read is necessary [..] Workarounds: (#) For AHB & APB peripherals, a dummy read to the peripheral register has been inserted in each LL_{BUS}_GRP{x}_EnableClock() function. @endverbatim ****************************************************************************** * @attention * * <h2><center>© COPYRIGHT(c) 2017 STMicroelectronics</center></h2> * * Redistribution and use in source and binary forms, with or without modification, * are permitted provided that the following conditions are met: * 1.
