6.15-stable review patch. If anyone has any objections, please let me know.

From: Thierry Reding treding@nvidia.com
[ Upstream commit 78eb18020a88a4eed15f5af7700ed570642ff8f1 ]
The IVC code is library code that other drivers need to select if they need that library. However, if the symbol is user-selectable this can lead to conflicts.
Fix this by making the symbol only selectable for COMPILE_TEST and add a select TEGRA_IVC to TEGRA_BPMP, which is currently the only user.
