Commit c2c2ce1e9623 ("drm/amd/display: Optimize passive update planes.")
removed the last caller of context_timing_trace.
Remove it.

With that gone, no one is now looking at the 'timing_trace' flag, remove
it and all the places that set it.

[Why]
There are some issues which customer only can provide full
dump for analyze, without register history, it's hard to
debug HW status.

[How]
1. Put register read/write into WPP log so we can trace the logs
from full memory dump.
2. MALL doesn't add into WPP, add it.

sampling_rate is an uint8_t but is assigned an unsigned int, and thus it
can overflow. As a result, sampling_rate is changed to uint32_t.

Similarly, LINK_QUAL_PATTERN_SET has a size of 2 bits, and it should
only be assigned to a value less or equal than 4.

This fixes 2 INTEGER_OVERFLOW issues reported by Coverity.

<id>f82200703434522f1b35d38bdef02486d22b2f25</id>
<content type='text'>
[Why]
Make SPL library dc-independent so it can be reused by other
 components

[How]
Create separate set of fixed31_32 calls in SPL
Make all inputs and outputs to SPL use primitive types
For ratios and inits, return as uint32 from SPL.  So
 add conversion from uint32 back to fixed point in
 SPL-to-dc translate function
