platform/x86: ideapad-laptop: use msecs_to_jiffies() helper instead of hand-crafted formula
The current code used a hand-crafted formula to convert milliseconds to
jiffies, replace it with the msecs_to_jiffies() function. Furthermore,
use a while loop instead of for loop for shorter lines and simplicity.
