Fill in asic family specific versions rather than

disable sw swapping of the rtpr writeback value on
r6xx+ since the hw does it for us. Fixes bogus

We need more control over the ordering of dpm init with
respect to the rest of the asic. Specifically, the SMC
has to be initialized before the rlc and cg/pg. The pm
code currently initializes late in the driver, but we need
it to happen much earlier so move pm handling into the asic
specific callbacks.
This makes dpm more reliable and makes clockgating work
properly on CIK parts and should help on SI parts as well.

Right now it's called right after enable, but after

drm/tegra: Changes for v3.14-rc1
This series of changes brings DRM panel support as well as initial code
to register DSI hosts and peripherals and bind them to DSI drivers. The
panel and DSI code are both used by the simple panel driver.
The Tegra-specific changes build on top of this work to add support for
various panels found on Tegra boards. New drivers enable the DSI host
found on Tegra114 and a special hardware block that calibrates the pads
used for DSI and CSI. The host1x and the display controller drivers gain
basic Tegra124 support. To round of the new features, the DRM driver now
sports a very simple PRIME implementation.
In addition there are various improvements such as the host1x API being
exported so that client drivers (like the Tegra DRM driver) can be built
as modules. HDMI now does better power management and legacy FBDEV can
now be disabled via Kconfig (though it's still enabled by default). A
few sparse warnings have been squashed and various parts of the code
have become more robust.

A lot of the modern userspace is capable of working without the legacy
fbdev support. kmscon can be used as a replacement for the framebuffer
console, and KMS X drivers create their own framebuffers.
Most people don't have a system where all of this works yet, though, so
leave support enabled by default.

When an output is disabled, its DPMS mode is usually set to off. Instead
of only disabling the panel (if one is attached), turn the output off
entirely to save more power.
HDMI doesn't have any panels attached, so it previously didn't save any
power at all. With this commit, however, the complete HDMI interface
will be turned off, therefore allowing an attached monitor to go into a
standby mode.

The DRM core doesn't track enable and disable state of encoders and/or
connectors, so calls to the output's .enable() and .disable() are not
guaranteed to be balanced. Track the enable state internally so that
calls to regulator and clock frameworks remain balanced.
