AArch32: Add assembly helpers
This patch adds various assembly helpers for AArch32 like :
* cache management : Functions to flush, invalidate and clean
cache by MVA. Also helpers to do cache operations by set-way
are also added.
* stack management: Macros to declare stack and get the current
stack corresponding to current CPU.
* Misc: Macros to access co processor registers in AArch32,
macros to define functions in assembly, assert macros, generic
`do_panic()` implementation and function to zero block of memory.
