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.

In order to simplify maintenance of dts files for
stm32f1 series, introduce a stm32f1.dtsi file which
represent the smallest common denominator of IPs in
the family.
Besides, stm32f103Xe includes stm32f103xb, as it is a
extension of this SoC.
