[PATCH 1/2] usb: xhci: move Primary Interrupter IMODI setup

[Niklas Neronin <niklas.neronin@linux.intel.com>]

Move IMODI programming into the Primary Interrupter initialization path,
keeping all interrupter-related setup in a single place.

xHCI platform drivers set 'xhci->imod_interval' well before xhci_init()
is called, so the value is available when the Primary Interrupter is
initialized.

The IMODI value does not change unless explicitly written by software.
See xHCI Specification v1.2, section 5.5.2.2.
