common/i2c: Improve port number validation in i2c_set_freq
This adds additional checks to the port number validation in
i2c_set_freq. get_i2c_port could potentially return a NULL pointer, so
check for that. Also, when DYNAMIC_SPEED is not enabled on a port,
return ERROR_UNIMPLEMENTED instead of ERROR_INVAL.
BRANCH=none
BUG=b:201039003
TEST=with follow-on patches, switched I2C bus speed between 400 kHz
and 1 MHz.
