[v2,1/8] dt-bindings: tegra186-hsp: Add shared interrupts

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.
