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

fix(ulp): fixed lp-core not booting during sleep
...
LP core was unable to boot when system was in deepsleep.
This was due to lp uart init in LP rom using XTAL as clk source,
which is normally powered down during sleep.
This would cause lp uart to get stuck while printing ROM output,
and the app would never boot.
Also fixed wrong wakeup cause used by HP core for ULP wake up
