[PATCH 13&15/16 v2] ARM: ux500: Apply Device Tree settings for the DB8500 PRCMU

[lee.jones@linaro.org (Lee Jones)]

Subject: [PATCH 1/2] mfd/db8500-prcmu: Add Device Tree support and enable
 ux500 platforms

Here we see the db8500-prcmu driver obtain DT support. In its
current state, all we have to do is offer a matching compatible
node and the driver will register and initialise correctly. We
Also remove any initialisation completed in platform code to
prevent any device duplication.
