[ Upstream commit 552b7cb0eed12c184b3bdfcc262e96a954a2bc86 ]

The calcs folder has FPU code on it, which should be isolated inside the
DML folder as per https://patchwork.freedesktop.org/series/93042/.

This commit aims single-handedly to correct the location of such FPU
code and does not refactor any functions.

Changes since v2:
- Corrected problems to compile when DCN was disabled.
