crypto: fix and enable aes dma on G12B [1/1]

PD# SWPL-4823

Problem:
1. After stack optimization, stack memory cannot be
mapped as dma buffers and thus causing crypto dma failed to
generate correct result.
2. crypto dma was not enabled on G12B

Solution:
1. Move key_iv buffer from stack to memory provided by kzalloc
2. Enable crypto dma on G12B
3. Replace module_param with debugfs
4. Replace pr_err with dev_err

Verify:
verified on G12B
