[ARM] arm32: Add support for ARMv6 processors

This extends arm32 CPU support for ARMv6 processors.

The ARMv7 MMU is fully backward compatible to ARMv6 MMU.

Also, ARMv6 instruction-set is sub-set of ARMv7 instruction-set. In fact, ARMv7 has only few additional instructions.

[ARM] Add Raspberry Pi (or BCM2835 SOC) support

This is initial board support for Raspberry Pi or BCM2835 SOC.

This patch enables us to boot vmm.bin on Raspberry Pi emulated by QEMU.

The source for QEMU with Raspberry Pi support resides in rpi branch of https://github.com/Torlus/qemu

In future, we will be able to boot a ARMv6 guest on Raspberry Pi (emulated by QEMU or real HW).
