sys/arm: Minor spelling fixes.

Only affects comments: no functional change.

ARM: Remove never used cpu_tlb_flushI and cpu_tlb_flushI_SE() functions
and their implementations.

arm11_sleep is no longer needed, remove it.

Remove unused cpufunc arm11 and armv6 code. While here only define the
remaining functions in the context we use them in.

Remove code under PMAP_CACHE_VIVT that is not compiled anymore.

This is for ARMv4/ARMv5 and it doesn't belong in ARMv6 code.

Add an END macro to ARM. This is mostly used to tell gas where the bounds
of the functions are when creating the EABI unwind tables.

Merge fix for hang on ARM11 from NetBSD

Merging projects/armv6, part 1

Cummulative patch of changes that are not vendor-specific:
- ARMv6 and ARMv7 architecture support
- ARM SMP support
- VFP/Neon support
- ARM Generic Interrupt Controller driver
- Simplification of startup code for all platforms

Final whitespace trim.

Merge support from p4 (from NetBSD) for arm9e and arm10, arm11 cores. Not
yet connected to the build, but reduces diffs to p4 repo.
