compute_timing_parameters() is only used by i2c_init(). Signed-off-by: Kinza Qamar <kqzaman@lowrisc.org>

Now that we are chip level I2C Host/Device tests, renaming existing i2c/smoketest with the functionality of the test seems reasonable. Signed-off-by: Kinza Qamar <kqzaman@lowrisc.org>
The only difference b/w them was that i2c_wait_read_finish() wasn't checking cmd_complete field of the intr_state register. In host mode, this interrupt is raised if the host issues a repeated START or terminates the transaction by issuing STOP. But OT's programming guide doesn't say anything about checking that field in case of a read transfer. I think it is better to check that field in case of Reads as it basically means that the transfer is completed. This also reduce the need of having 2 separate functions with just a difference of not checking cmd_complete field of the intr_state register. Signed-off-by: Kinza Qamar <kqzaman@lowrisc.org>
