Created a new directory called bsp (board support package) to hold
board or system on chip specific code. The idea is the following.

During startup machine.board_id is now determined. The kernel can now
at runtime determine how to configure itself and does so.

. set 'done' once initialized so 32-bit read frc works,
thanks to keesj
. make sure the software-implemented upper 32 bit of the 64-bit
"tsc" value works OK by adding an assert in one of its calls

The Cycle CouNTer on ARM cannot be used reliably as it wraps around
rather quickly and can be altered by user space (on Minix). Furthermore,
it's buggy when wrapping and is not implemented at all on the Linaro
Beagleboard emulator.
This patch programs GPTIMER10 as a free running clock at 1.625 MHz (it
doesn't generate interrupts). It's memory mapped into every process,
which enables libsys to provide micro_delay().

Due to the ABI we are using we have to use the earm architecture
moniker for the build system to behave correctly. This involves
then some headers to move around.
There is also a few related Makefile updates as well as minor
source code corrections.
