drm/amd/display: Remove double checks for debug.enable_mem_low_power.bits.cm

[Why]
A variety of the 3DLUT handling functions check
`debug.enable_mem_low_power.bits.cm` both in the caller and function.
This is unnecessary overhead.

[How]
For each of them reduce to just checking just in caller or function.
