Split the _init() function into something that can be done early and
the rest which can be done late (during drivers inits).
This is done in preperation to remove the hwmod dependency to do all
clock inits (which inturn need clockdomain and other frameworks to be
in place) and module resets quite early in boot, and instead do these
on demand when the drivers initialize.
