This patch only creates sections to regroup functions by usage.
This will help to integrate the GCM support patch later by making the
difference between shared/common and specific code. Hence current
sections are:

- Shared functions: common code which will be reused by the GCM support.
- CPU transfer: handles transfers monitored by the CPU (PIO accesses).
- DMA transfer: handles transfers monitored by the DMA controller.
- AES async block ciphers: dedicated to the already supported block ciphers
- Probe functions: used to register all crypto algorithms.
