When dpm was merged, I added a new asic struct for
rv6xx, but it never got properly updated when the
hdmi callbacks were added due to the two patch sets
being developed in parallel.

This is a partial revert of c6cf7777.

We need to take into account the clk voltage dependencies of the
board.  Not doing so can lead to stability issues on certain
boards if the clks exceed the levels in the dep tables.

DPM already takes that into account, so for optimal performance,
use DPM.

This patch adds a helper function to fetch the max clock
from the voltage clock dependecy tables.  Clocks above that
level tend to be unstable and will require additional driver
tweaks in order to work properly.

This patch implemented the helper function to fetch the max clocks
from the dependency tables.  The following patches implement the
per-asic clock filtering.

Otherwise the system will burn even brighter and worse, leave the user
wondering what's going on exactly.

Since we already have a panic handler which will (try) to restore the
entire fbdev console mode, we can just bail out.  Inspired by a patch from
Konstantin Khlebnikov.  The callchain leading to this, cut&pasted from
Konstantin's original patch:

callstack:
panic()
bust_spinlocks(1)
unblank_screen()
vc->vc_sw->con_blank()
fbcon_blank()
fb_blank()
info->fbops->fb_blank()
drm_fb_helper_blank()
drm_fb_helper_dpms()
drm_modeset_lock_all()
mutex_lock(&dev->mode_config.mutex)

Note that the entire locking in the fb helper around panic/sysrq and kdbg
is ...  non-existant.  So we have a decent change of blowing up
everything.  But since reworking this ties in with funny concepts like the
fbdev notifier chain or the impressive things which happen around
console_lock while oopsing, I'll leave that as an exercise for braver
souls than me.

After a vmalloc failure in ttm_dma_tt_alloc_page_directory(),
ttm_dma_tt_init() will call ttm_tt_destroy() to cleanup, and end up
inside the driver's unpopulate() hook when populate() has never yet
been called.

On nouveau, the first issue to be hit because of this is that
dma_address[] may be a NULL pointer.  After working around this,
ttm_pool_unpopulate() may potentially hit the same issue with
the pages[] array.

It seems to make more sense to avoid calling unpopulate on already
unpopulated TTMs than to add checks to all the implementations.
