irqchip/irq-imx-gpcv2: Silence "fall through" warning

Marc Zyngier · Marc Zyngier · commit 893b0aff9a7a · 2018-12-15T09:10:46.000Z
The -Wimplicit-fallthrough option requires that the /* fall through */
comment is placed in the 'case' statement that falls through, rather
than in the following one. Case seems to matter as well.
