ARM: imx: make the imx timer driver implementation independent of SoCs.

There are 4 versions of the timer hardware on Freescale MXC hardware. --Version 0: MX1/MXL
--Version 1: MX21, MX27.
--Version 2: MX25, MX31, MX35, MX37, MX51, MX6Q(Rev1.0) --Version 3: MX6DL, MX6SX, MX6Q(Rev1.1+)

This patch has removed the SoC related codes, and implemented the driver directly upon the hardware timer IP version. The new timer driver has redesigned the internal APIs, and limited the use of global variables as well.

As the new driver has become independent of the SoCs, it has been moved from the directory arch/arm/mach-imx into the directory drivers/clocksources.
