common/i2c: Implement i2cspeed console command
This adds the "i2cspeed port [speed]" console command. If only the port
number is given, then the current port bus speed is reported. With 2
arguments, the port bus speed is changed. Valid speeds are 100, 400,
1000 and the unit is kHz.
BRANCH=none
BUG=b:201039003
TEST=with follow-on patches, switched I2C bus speed between 400 kHz
and 1 MHz.
