x86/intel/moorestown: Change intel_scu_devices_create() to __devinit

The allmodconfig hits:

 WARNING: vmlinux.o(.text+0x6553d): Section mismatch in
          reference from the function intel_scu_devices_create() to the
          function .devinit.text: spi_register_board_info()
	  [...]

This patch marks intel_scu_devices_create() as devinit because
it only calls a devinit function, spi_register_board_info().
