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

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.

  x86, mrst: share APB timer code with other platforms
  clocksource: platform driver for APB timers
