Subject: [PATCH 01/21] genirq: Set IRQF_COND_ONESHOT in devm_request_irq().

The flag IRQF_COND_ONESHOT was already force-added to request_irq()
because the ACPI SCI interrupt handler is using the ONESHOT and it
breaks all shared handler.
devm_request_irq() needs the same change since some users, such as
int0002_vgpio, are using this function instead.

Add IRQF_COND_ONESHOT to flags passed to devm_request_irq().

Fixes: c37927a203fa2 ("genirq: Set IRQF_COND_ONESHOT in request_irq()")
