PM branch updates: 3430sdp and omap3evm results

[Kevin Hilman <khilman@deeprootsystems.com>]

Hello,

I've updated the PM branch with a couple of fixes that get it working
on the 3430SDP.

For it to work on the SDP, you need the latest u-boot from the
omapzoom u-boot tree[1].  This fixes the problems I was having with
the D2D clockdomain remaining active or hanging upon clock disable.

For omap3evm, it is not hitting retention because it uses the GPIO
debounce feature for the touchscreen and the GPIO debounce clocks are
not disabled in idle or suspend.  As a temporary hack, you can test
the patch below[2] which simply doesn't call the gpio debounce
functions for the touchscreen.  In the meantime, I'm working on a
patch to disable the debounce clocks on idle.
