[RFC PATCH 0/2] Permit reuse of APB timers on other platforms

[Jamie Iles <jamie@jamieiles.com>]

These patches allow the APB timers to be used by platforms other than
x86.  The first patch moves the actual timer handling and
clocksource/clock_event_device abstraction into drivers/clocksource and
converts x86 to use this.  The second patch adds a platform_driver to
allow other systems to use them.

I've tested these on an ARM platform with NO_HZ but I don't have an x86
platform with these timers that I can test them on so that's just
compile tested.
