ir: remove irq affinity in hard decode mode [1/1]

Browse Source 
PD#SWPL-9797

Problem:
ir irq is binded to cup 1 and will re-set in every resume process.
cup 0 wakeup first in resume, if there comes a irq during resume in
a critical time it may occurs concurrency.

Solution:
remove irq affinity in hard decode mode and only use it in learning
mode.

Verify:
