From: Jim Quinlan <jim2101024@xxxxxxxxx>
Because regulators are started with subsys_initcall(), and gpio references may
be contained in the regulators, it makes sense to start the brcmstb-gpio's with
a subsys_initcall(). The order within the drivers/Makefile ensures that the
gpio initialization happens prior to the regulator's initialization.
We need to unroll module_platform_driver() now to allow this and have custom
exit and init module functions to control the initialization level.
