[Why]
The only place where state->max_bpc is updated on the connector is
at the start of atomic check during drm_atomic_connector_check. It
isn't updated when adding the connectors to the atomic state after
the fact. It also doesn't necessarily reflect the right value when
called in amdgpu during mode validation outside of atomic check.

This can cause the wrong bpc to be used even if the max_requested_bpc
is the correct value.

[How]
Don't rely on state->max_bpc reflecting the real bpc value and just
do the min(...) based on display info bpc and max_requested_bpc.

We need to set certain power gating flags after we determine
if the firmware version is sufficient to support gfxoff.
Previously we set the pg flags in early init, but we later
we might have disabled gfxoff if the firmware versions didn't
support it.  Move adding the additional pg flags after we
determine whether or not to support gfxoff.

The initial support for dynamic ftrace trampolines in modules made use
of an indirect branch which loaded its target from the beginning of
a special section (e71a4e1b ("arm64: ftrace: add support for far
branches to dynamic ftrace")). Since no instructions were being patched,
no cache maintenance was needed. However, later in be0f272b ("arm64:
ftrace: emit ftrace-mod.o contents through code") this code was reworked
to output the trampoline instructions directly into the PLT entry but,
unfortunately, the necessary cache maintenance was overlooked.

Add a call to __flush_icache_range() after writing the new trampoline
instructions but before patching in the branch to the trampoline.

The R-Car LVDS encoder units support dual-link operations by splitting
the pixel output between the primary encoder and the companion encoder.

Currently the companion encoder fails at probe time, causing the
registration of the primary to fail as well, preventing the whole DU unit
from being registered at all.

Fix this by not bailing out from probe with error if the
"renesas,companion" property is not specified.
