[PATCH 5.15 350/917] drm/amd/display: Pass display_pipe_params_st as const in DML

Greg Kroah-Hartman

From: Harry Wentland <harry.wentland@amd.com>

[ Upstream commit 22667e6ec6b2ce9ca706e9061660b059725d009c ]

[Why]
This neither needs to be on the stack nor passed by value
to each function call. In fact, when building with clang
it seems to break the Linux's default 1024 byte stack
frame limit.

[How]
We can simply pass this as a const pointer.

This patch fixes these Coverity IDs
