tn8: modem: reduce timeout wakelock to 1s

1. The kernel resume (from LP0 to the time when app tasks start unfreezing) is shorter than 200ms.
When app tasks start running, the RIL/framework/app will hold their wake lock to block suspending.
Furthermore, tegra_usb_modem_post_remote_wakeup() in tegra_usb_modem_power.c will hold
another timeout (1 second) wake lock, which should start later than the wake lock "tegra-ehci.1".
So, 1s timeout for wake lock "tegra-ehci.1" in kernel should be enough.
2. Per our experience, many system resume/suspend (with screen off) caused by remote wake-up is
able to finish in 1.5 seconds, or even shorter. So, 3 seconds timeout could cause more unnecessary power consumption.
