[HOW]
The sequence, from HW:
a. 127 -> 126

Set DCCG_FIFO_ERRDET_OVR_EN = 0
Write DENTIST_DISPCLK_RDIVIDER = 126

Because of frequency stepping, sequence a can be executed to change the
divider from 127 to any other divider value.

b. 126 -> 127

drm/amd/display: Partition DPCD address space and break up transactions

[WHY]
SCR for DP 2.0 spec says that multiple LTTPRs must not be accessed in a
single AUX transaction.
There may be other places in future where breaking up AUX accesses is

be read all together in a single DPCD transaction. Rather than force callers to

read, and only return back the values the caller asked for.
This does not affect DPCD writes.

[HOW]
Create an additional layer above AUX to perform 'checked' DPCD
transactions.
Iterate through an array of DPCD address ranges that are marked as being
contiguous. If a requested read falls within one of those ranges, extend
the read to include the entire range.
After DPCD has been queried, copy the requested bytes into the caller's
