[PATCH 4.19.y-cip 12/22] thermal: rcar_gen3_thermal: Fix init value of IRQCTL register

Biju Das <biju.das@...>

From: Hoan Nguyen An <na-hoan@...>

commit ed1b1ac1425b3d4399553411f305ce12fb3a6c54 upstream.

Fix setting value for IRQCTL register. We are setting the last 6 bits
of (IRQCTL) to be 1 (0x3f), this is only suitable for H3ES1.*, according
to Hardware manual values 1 are "setting prohibited" for Gen3.
