DC was using compile time initialization of register addresses using
SR_* macros and their variants. These have been converted to use runtime
initialization.
The REG_STRUCT macro is a definition that is added to SR_* macros.
During initialization, this must be defined before SR_* macros are
invoked, which are in turn invoked through various IP initialization macros.

[WHY]
Reprogramming the stream despite no changes in ODM combine mode.
Reprogramming the stream would cause intermittent black screen on
display which could only be recovered through enable/disable sequence.
[HOW]
Fixed bug where we detected a change in ODM combine mode despite ODM
combine mode being disabled. Also removed code which required stream to
be reprogrammed once a change in ODM combine mode was noticed. Lastly we
do not support dynamic ODM switching for HDMI TMDS and FRL on DCN32,
therefore we never want to change its ODM policy.

[Why & How]
When multiple displays are used, the underlying framebuffers could be
two separate framebuffers, or a single large framebuffer. Fix the
calculation logic for CAB to account for large framebuffer. Current
logic assumes that any FB that the plane points to are independent. When
a single FB is used on the system, this does 2 times allocation.
Add a check to prevent duplicate allocation by checking if the base
addresses are the same, and then ensuring that the if we allocate using
the pitch, whole of the other fbs will be accounted for in the first
allocation.

ld: drivers/gpu/drm/amd/display/dc/dml/display_mode_lib.o uses hard float, drivers/gpu/drm/amd/display/dc/dcn30/dcn30_optc.o uses soft float
ld: failed to merge target specific data of file drivers/gpu/drm/amd/display/dc/dcn30/dcn30_optc.o
This error happened because of the function optc3_set_vrr_m_const. This
function expects a double as a parameter in a code that is not allowed
to have FPU operations. After further investigation, it became clear
that optc3_set_vrr_m_const was never invoked, so we can safely drop this
function and fix the ld issue.

[why]
Unbounded request logic in resource/DML has some issues where unbounded
request is being enabled incorrectly. SW today enables unbounded request
unconditionally in hardware, on the assumption that HW can always
support it in single pipe scenarios.
This worked until now because the same assumption is made in DML. A new
DML update is needed to fix a bug, where there are single pipe scenarios
where unbounded cannot be enabled, and this change in DML needs to be
ported in, and dcn32 resource logic fixed.
[how]
First, dcn32_resource should program unbounded req in HW according to
unbounded req enablement output from DML, as opposed to DML input.
Second, port in DML update which disables unbounded req in some
