It's technically an MC register so make sure we initialize it
in the MC module rather than the gfx module. Since other bits
in the same register are used to enable ATC CG features make
sure we apply the golden setting first.

We need this for more than just DCE. Move it out of the DCE modules
and into the device code. This way we can be sure the scratch registers
are initialized properly before we run asic_init which happens before
DCE IPs are restored.
Fixes atombios hangs in asic_init.

Make sure we have at least one port before attempting to register a
console.
Currently, at least one driver binds to a "dummy" interface and requests
zero ports for it. Should such an interface also lack endpoints, we get
a NULL-deref during probe.

The following patchset contains Netfilter fixes for your net tree,
they are:
1) Fix compilation warning in xt_hashlimit on m68k 32-bits, from
Geert Uytterhoeven.
2) Fix wrong timeout in set elements added from packet path via
nft_dynset, from Anders K. Pedersen.
3) Remove obsolete nf_conntrack_events_retry_timeout sysctl
documentation, from Nicolas Dichtel.
4) Ensure proper initialization of log flags via xt_LOG, from
Liping Zhang.
5) Missing alias to autoload ipcomp, also from Liping Zhang.
6) Missing NFTA_HASH_OFFSET attribute validation, again from Liping.
7) Wrong integer type in the new nft_parse_u32_check() function,
from Dan Carpenter.
8) Another wrong integer type declaration in nft_exthdr_init, also
from Dan Carpenter.
9) Fix insufficient mode validation in nft_range.
10) Fix compilation warning in nft_range due to possible uninitialized

Because pm_runtime_set_suspended() invokes __pm_runtime_set_status(), which
can fail, pm_runtime_set_suspended() can also fail.
Instead of hiding a potential error, let's propagate it by converting
pm_runtime_set_suspended() from a void to return an int. In this way users
are able to check the error code and act accordingly.
