xhci: Add helper to set an interrupters interrupt moderation interval
[ Upstream commit ace21625878f78708b75b7a872ec7a0e2ed15ca4 ]
Add a helper to set the interrupt moderation interval for an interrupter.
Each interrupter can have its own moderation value.
Hardware has a 16bit register for the moderation value, each step is 250ns.
Helper function imod_interval argument is in nanoseconds.
Values from 0 to 16383750 (250 x 0xffff) are accepted.
0 means no interrupt throttling.
