ARM: imx: clean up machine mxc_arch_reset_init_dt reset init
System restart mechanism has been changed with the introduction of "kernel restart handler call chain support". The imx2 watchdog based restart handler has been moved to the driver, and these restart can be removed from the machine layer. This patch cleans up the device tree version machine reset init with mxc_arch_reset_init_dt and removes corresponding .restart handler, for the .init_machine that can be handled by system default after removing the mxc_arch_reset_init_dt, the .init_machine is also removed.
