Subject: [PATCH 1/2]: twl4030: register twl4030-pwrbuttonas a child of 
     twl4030-core.c

'twl4030-pwrbutton' was already made as a platform_driver so it can
be registered as a child of twl4030-core.c.

But adding twl4030-pwrbutton as our child in twl4030-core is missing
currently. This patch adds it.
