kernel/arm: clean up arch-specific defines

* align fault syndrome and fault address register naming with
ARM Architecture Reference Manual (i.e. IFSR, DFSR, IFAR, DFAR)
* move PSR bitfield defines to arch_cpu_defs.h

kernel/arm: move exception handler stacks to data segment

Exception handler stacks used to be defined in the text segment
which doesn't work very well once we enable memory access permissions
as the text segment is read-only.

arm/arch_exceptions.S: Replace spsr_all with spsr

After a quick look at binutils, they seem to be equal, however, Clang
does not accept the _all one.

Add missing function end macro.

Whitespace cleanup only.

ARM: Cleanup of port support code.

This also implements the fault handler correctly now, and cleans up the
exception handling. Seems a lot more stable now, no unexpected panics or
faults happening anymore.

ARM: Initial implementation of interrupt/exception handling.

This contains both the common ARM(v5) vector handling as well as
the PXA(verdex) specific interrupt controller code, to be seperated
when ARM support for FDT is implemented.

Functional enough to handle interrupts, needs work on KDL support.
