This patch removes the call to arch_cpu_init() in the SPL U-Boot version. As SPL does not need all the configuration done in this function. And also does not need the reconfiguration of the internal register address to 0xf1000000. This will be done by the main U-Boot later on. This also fixes a problem with the timer not beeing initialized on AXP, as needed for the mdelay in the setup_usb_phys(). This will now only be called once in main U-Boot.
