ahci: Adjust SATA timeouts for hard disk (spinup delay & command timeout)
Note: These are timeout values and not delay values, so the event being timed out will complete whenever it is actually ready, with a measurement granularity of 1 millisecond, up till the timeout value. Therefore, there is no effect on SSD booting. The values were determined by instrumenting the code and measuring the actual time taken by several different models of HDD for each of the parameters and then adding 50% more for the spinup value and just doubling the command timeout value.
