rtc: tps6586x: Fix error in RTC tick calculations

In the TPS6586x PMU/PMIC RTC support code, when
converting from seconds to ticks using a shift
operator, the most significant bits were being lost
due to seconds being a 32-bit value and ticks being
a 64-bit value.  A hard cast was added to avoid this
loss.

usb: ehci: tegra: remove reschedule rh_timer

Reschedule rh_timer may cause usb device resume fail, as rh_timer may be
timeout and send USB_REQ_GET_STATUS SETUP control transfer by the time when
the device is handling clear suspend feature, which in turn the device may
drop clear suspend feature request.

Actually on port resume case, the host driver don't need to reschedule
rh_timer to check port status. The host driver will check port status right
after suspend feature is cleared.
