drm/tegra: dsi: detect possible_crtcs

Other platforms allow dsi across multiple heads, but some have
one or more heads disabled. This results in a mismatch between
possible_crtcs and the real crtc mask. Apply the same
`tegra_output_find_possible_crtcs` function to DSI to properly
detect.

+description:
+  The Rohm BM92TXX is a family of USB Type-C and Power Delivery
+  controllers with an integrated MCU. The host communicates with the
+  device over I2C and is notified of state changes through a dedicated
+  interrupt line.
