Subject: [PATCH] i2c: spacemit: drop IRQF_ONESHOT flag from IRQ request

In commit aef30c8d569c ("genirq: Warn about using IRQF_ONESHOT without a
threaded handler")[1], it will check IRQF_ONESHOT flag in IRQ request,
and gives a warning if there is no threaded handler. Drop this flag to
fix this warning.
