The ProcessAuxChannel table on some rv635 boards assumes
the divmul members are initialized to 0 otherwise we get
an invalid fb offset since it has a bad mask set when
setting the fb base.  While here initialize all the
atom interpretor elements to 0.

Since the original merge of nouveau to upstream kernel, we were assuming
that nv90 (and later) cards have 32 lines.

Based on mmio traces of the binary driver, as well as PBUS error messages
during read/write of the e070/e074 registers, we can conclude that nv92
has only 16 lines whereas nv94 (and later) cards have 32.

The current logic is wrong since we send fw->size >> 8 to the
card. Rounding the size up by 0x100 and 0x1000 didn't seem to help,
the card still hung, so go back to what the blob does -- 0x40000.

Disable cac setup on SI for now since it causes
strange performance level restrictions on certain
cards.  I suspect there may be issues with some of
the 64 bit fixed point double emulation that is used
to set up those parameters.  I need to double check
the math before this can be re-enabled.

Coarse grain clockgating causes problems with reclocking on
some cards and powergating (verde only) causes problems with
ring initialization.  The proper fix (restructuring the init
sequences) is too invasive for 3.11 so just disable them for
now.
