change(lp_core): changed wakeup time calc to use a precomputed tick value

Browse Source 
Previously we would calculate the wakeup ticks upon every wakeup using the lp-timer clock frequency,
but this caused the binary to pull in software division functions, increasing the binary size.

This value is now precalculated by the hp-core when we configure the ULP. This saves about 1k bytes.
