This isn't needed in this file. Instead, devices.c should include
it. Plus, pm.c needs to include mach/pm.h, otherwise sparse gives
the following warnings:

  CHECK   arch/arm/mach-cns3xxx/pm.c
pm.c:26:6: warning: symbol 'cns3xxx_pwr_clk_dis' was not declared. Should it be static?
pm.c:35:6: warning: symbol 'cns3xxx_pwr_power_up' was not declared. Should it be static?
pm.c:47:6: warning: symbol 'cns3xxx_pwr_power_down' was not declared. Should it be static?
pm.c:121:10: warning: symbol 'usb_pwr_ref' was not declared. Should it be static?

I've fixed it up, and applied the patch to cns3xxx tree.

Thanks!
