regmap-irq: set IRQF_ONESHOT flag to ensure IRQ request
Since commit 1c6c69525b40eb76de8adf039409722015927dc3 ("genirq: Reject bogus threaded irq requests") threaded IRQs without a primary handler need to be requested with IRQF_ONESHOT, otherwise the request will fail. The %irq_flags flag is used to request the threaded IRQ and is also a parameter of the caller. Hence, we cannot be sure that IRQF_ONESHOT is set. This change avoids the potentially missing flag by setting IRQF_ONESHOT when requesting the threaded IRQ.
