It appears that grub2 will pass framebuffer info via EFI,
this causes the vram reserve to fail, so kick out efifb
earlier before cirrus loads.

We still don't understand why this fails exactly, but if fails way
too often for a simple debug information. Furthermore the current
ducttape should prevent the gpu from getting stuck at low frequencies.

Hence tune down the dmesg noise.

Note that the known failure case is that the register read returns 0
when the gpu gets confused.

v2: Add comments about the known failure case.

The existing assertions were written under the assumption that we wanted
to test the related PLL to a CRTC. With the split of PLL into a
separately managed entity which may be shared amongst CRTCs, we need to
pass in both the CRTC and the PLL to the assertion routine.
Occassionally, this means passing NULL for the CRTC as we wish to check
the status of the PLL irrespective of the current CRTC.

In order to avoid missed down-interrupts when coming out of RC6, it is
advised that we always reset the down-threshold upon a PM event. This is
due to that the PM unit goes through a little dance when coming out of
RC6, it first brings the GPU up at the lowest frequency then a short
time later it restores the thresholds. During that interval, the
down-interval may expire and the interrupt be suppressed.

Now aware of the dance taking place within the GPU when coming out of
RC6, one wonders what other writes need to be queued in the fifo buffer
in order to be properly sequenced; setting the RP state appears to be
one.

being a master channel list still.  This is changing, slowly.
