[PATCH/RFC 1/3] thermal: rcar_gen3_thermal: Modify the shared irq with initialization

[Khiem Nguyen]

In R-CAR Gen3 series, it has some thermal sensors. The interrupt I/F
that can be used in thermal sensors is three. So it should be used
the interrupt I/F as shared.

This patch changes the shared settings for the thermal interrupts.
