staging: ccree: use signal safe completion wait

Browse source

We were waiting for a completion notification of HW DMA
operation using an interruptible wait which can result
in data corruption if a signal interrupted us while
DMA was not yet completed.

Fix this by moving to uninterrupted wait.

Fixes: abefd6741d ("staging: ccree: introduce CryptoCell HW driver").
