This patch adds the possibility to call a board specific i2c bus reset routine for the fsl_i2c bus driver, and adds this option for the keymile kmeter1 board.

The deblock sequence for this board is implemented and tested in the following way:

CR = 0x20 (release SDA and SCL pin) CR = 0xa0 (start read) dummy read dummy read if 2. dummy read == 0x00 3. dummy read

CR = 0x80 (SDA and SCL now 1 SR = 0x86) CR = 0x00 (Modul reset SR=0x81) CR = 0x80 (SDA and SCL = 1, SR = 0x81)
