HSP interrupts can be routed through exposed "shared interrupts". These
interrupts can be mapped to various internal interrupt lines. Add
interrupt properties for shared interrupts to the tegra186-hsp device
tree bindings. At the same time, add the compatibility string for
tegra194-hsp, which is backwards compatible with tegra186.

Notes:
v2:
- Edited commit message to not say that doorbell interrupts cannot be
routed to shared interrupts.
- Added tegra194 compatibility string.
