fix(ulp): fixed lp-core not booting during sleep

Browse Source 
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
