XHCI allows interrupt moderation using imod_interval at 250ns increments. Add DT parameter to specify this imod_value for targets mainly with single CPU to reduce CPU interrupt loads. This allows better balance between CPU usage and performance. CRs-fixed: 1019219 Change-Id: Id479c162da6492caff4dd83de4054fee63b6abc5 Signed-off-by: Manu Gautam <mgautam@codeaurora.org>
