Gao Feng 3194ef0e7c arch/xtensa: set PS.EXCM initial value to 1 while new thread created 
To avoid level-1 interrupt break retrieve PC/A0/SP/A2 register,
PS.EXCM set to 1 by CPU HW while handling exception/interrupt.

But if context switching happens and new thread created,
the thread initial value of PS.EXCM is used.

Same behevior as ESP-IDF code:
