Subject: drm/amd/display: add NAVI14 in resource construct
Git-commit: 2ebe177344d79bc61294d4365376978610d316c3
Patch-mainline: v5.4-rc1
References: bsc#1152489

Change the pipes to 5 if the asic is nv14

This is a temp patch, there was some refactor in the dml part of the code.
which is not in this branch. for now this is good, we can implement this
properly once we have an updated branch.
