According to ATA specification, maximum IORDY pulse width is 1250ns,
so I'll set timeout to 2ms (I should check this before posting the driver..).

2ms is far too big value... Should be 2us.

Ok, in this case, don't use jiffies. I guess it was already flawed because
jiffies doesn't get updated while you are in an interrupt handler.

You could use ktime_get to get a high-resolution time stamp to compare to,
but it depends on how accurate your clocksource is.
