[PATCH] Input: mc13783-pwrbutton - convert to use module_platform_driver()

[Axel Lin]

This patch converts mc13783-pwrbutton to use the module_platform_driver()
macro which makes the code smaller and a bit simpler.

Also staticise mc13783_pwrbutton_driver which is not used outside
this driver so no need to make the symbol global.
