NANO130: Enlarge timeout in CLK_WaitClockReady(...)

ccli8 · ccli8 · commit 7204858bdef0 · 2020-03-09T17:21:32.000+08:00
Most code doesn't check return code of CLK_WaitClockReady(...). Enlarge timeout to meet most cases.

lp_ticker initialization fails with this issue. Steps for reproducing:
1.  System runs in tickless from lp_ticker mode.
2.  Arm WDT reset.
3.  In next reset cycle, lp_ticker initialization fails (active flag doesn't become active).
