adl_ish_lite: Not enter D0i3

This increases D0i3 entering threshold to 3 seconds.

With orignial 50ms, we run into some power consumption issue.
ISH enters D0i3, wakes up every ~100ms and does DMA copy. DMA copy causes
host being waken up, and the time host stays in S0i3 is too short. Power
consumption also increases.

Changing threshold to 3 seconds, current ISH won't enter D0i3. It only
enter D0i2 and IPAPG. The power consumption is within range, also can
meet S0i3 requirement.

BUG=b:234136500
BRANCH=none
TEST=On Nirwen platform, pass S0ix test, can hit S0i3; and ISH power state
is D0i2.
