Import at91rm9200_time.c from mach-at91 as timer-atmel-st.c. Further cleanup is
required to get rid of the mach-at91 headers.

H Alexandre,

the global policy is to enable the timer from the platform Kconfig.

So it should be:

config ATMEL_ST
	bool
	select CLKSRC_OF if OF

and change the mach's Kconfig to select this driver for the corresponding platform.

  config CLKSRC_METAG_GENERIC
  	def_bool y if METAG
  	help
