Joel A Fernandes bbbaa37428 crypto: omap-aes - Use pm_runtime_put instead of pm_runtime_put_sync in tasklet 
After DMA is complete, the omap_aes_finish_req function is called as
a part of the done_task tasklet. During this its atomic and any calls
to pm functions should not assume they wont sleep.

The patch replaces a call to pm_runtime_put_sync (which can sleep) with
pm_runtime_put thus fixing a kernel panic observed on AM33xx SoC during
AES operation.

Tested on an AM33xx SoC device (beaglebone board).
To reproduce the problem, I used the tcrypt kernel module as:
modprobe tcrypt sec=2 mode=500
