Add resin key support to handle different types of key events

Describe "resin" in the commit text? or just call it same as power key
or different purpose?

You may want to document here why you still return as IRQ_HANDLED on the
error after reading the status register?

Any reason you don't want to create different driver for "resin" key? Is
this going to be physically different key on the platform? Please
describe why it needs to be part of the power key driver.
