ARM: Allow to mask data aborts
...
Sometimes it's useful to test if a memory operation works or
aborts. This adds data_abort_mask() to ignore data aborts and
data_abort_unmask() to enable them again. This is used in the
next step for the 'md' command so that illegal addresses just
show 'xxxxxxxx' instead of crashing the system.

ARN: fixup vector addresses for relocatable binaries
...
With relocatable binaries the vector addresses cannot be supplied by
the linker. This adds support for fixing them up during runtime.

ARM exceptions: Do not use hardcoded STACK_BASE
...
The exception handlers need some space to write to. Traditionally
this has been some stack space. This is not necessary at all, so
just use some variable and get rid of the compile time fixed stack
address.

ARM: Allow to compile in thumb-2 mode
...
This shrinks the resulting binary size by ~25%. Exceptions
are still handled in arm mode, so we have to explicitely
put .arm directives into the exception code. Thumb-2 mode
has been tested on i.MX51 Babbage board.

remove irq support fragments
...
We never had interrupt support in barebox and we have no plans to
add interrupt support. Even if we do I doubt the current fragments
of irq support are helpful, so remove them.

ARM: remove unused exception
...
The exception vector at 0x14 is not used on arm, so no need
to bind this address to a exception handler. Remove the
corresponding code
