'cat xxx_Count' to show the statistics. xxx: name of statistics, (Data, Transfer, Latency...) 'echo clear > Monitor' to clear snapshot of monitor statistics.

The current split between this and the fiq debugger is awkward and does not have any benefit (the interface between the two is also too simplistic). The fiq debugger code itself needs a lot of refactoring, part of which would be to split out some components that are arch indpendent. So, for now, move this very small piece back into the fiq_debugger. Change-Id: Ie4ec2a2f5d907be1691a0eb6ae9304aad29ecd14 Signed-off-by: Dima Zavin <dima@android.com>

This provides kernel_debugger() which can be called from an interrupt context low level debugger wedge to execute commands that inspect kernel state. It doesn't do much on its own.
