From: Axel Haslam <ahaslam+renesas@baylibre.com>

prepare generic power domain init function parameters to accept a pointer
to the states structure that describes the possible states that a power
domain can enter.

Also, as most platforms are not initializing states or latencies, add
pm_genpd_init_simple that allows platfroms to use a default single OFF
state with initial latencies set to 0.

There is no functional change, as support for multiple domains will be
added in subsequent patches.

Hi Axel,

Thanks for rebasing.

I ran into a compilation issue on ARM64 with defconfig.

Change in drivers/clk/qcom/gdsc.c is missing.

Thanks,

Ouch.. Sorry, i accidentally used linux-next branch from linux-pm tree..
and i missed a couple of platfroms that recently started using
genpd's..ill repost v10 based on the real linux-next.. sorry again..
