This patch switches to the desired I2C bus when the SNTP
network service is called. This can be configured using the
CONFIG_SYS_RTC_BUS_NUM define.
In my eyes this is a bad and quick hack, but the same as
was making for the date and dtt commands (commit: 0dc018e).
The right way would be to move all the hardware specific i2c
code down to the rtc driver layer.
