firmware: tegra: Fix IVC dependency problems

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.
