We really don't want to post the card at init, it takes a relatively
long time and isn't required, so split the resume path into
a startup path called by both init/resume and separate resume
entry point to do posting.

Before we use any of VRAM, we need to disable the VGA rendering
engine, this render text mode into a graphical framebuffer
for scanout, however it does this on vblank, and can end up
overwriting the GART table and r600 shader objects.

Someone on IRC reported problems after commit
95a8f1bf ('drm/radeon/kms: Move
radeon_clocks_init() call back after getting VRAM info.'). And indeed, at least
some ASIC vram_info hooks use the clock info obtained by
radeon_get_clock_info(). So, move that call out of radeon_clocks_init(), ahead
of the radeon_vram_info() call.

The drm_fb_helper shouldn't mess with CRTCs that aren't enabled or in
its initial config. Ideally it shouldn't even include CRTCs in its
initial config if they're not in use, but my old fix for that no longer
works.  At any rate, this fixes a real bug I was seeing where after a
console blank, both pipes would come back on, even though only one had
been enabled before that.  Since the other pipe had a bogus config,
this led to some screen corruption.

We sometimes lock IB then the ring and sometimes the ring then

about what data in the structs it actually locks. Define what I

GART static one time initialization was mixed up with GART
enabling/disabling which could happen several time for instance
during suspend/resume cycles. This patch splits all GART
handling into 4 differents function. gart_init is for one
time initialization, gart_deinit is called upon module unload
to free resources allocated by gart_init, gart_enable enable
the GART and is intented to be call after first initialization
and at each resume cycle or reset cycle. Finaly gart_disable
stop the GART and is intended to be call at suspend time or
when unloading the module.
