Kumar Gala 83643a2266 drivers: i2c: remove usage of bitfield access for cfg 
Cleanup I2C drivers to not use bitfield access for config information
and instead use accessor macros that use shifts & masks.  This is
cleanup towards removing the bitfield access in the future.

Kumar Gala 99c19c62e1 i2c: stm32: Remove usage of CONFIG_I2C_x_DEFAULT_CFG 
Stop using CONFIG_I2C_x_DEFAULT_CFG to get the initial value.  Since we
only support master mode we always default to it for initial config and
we get the bitrate from the device tree.
