irqchip/riscv-imsic: Report successful hardware retrigger
imsic_irq_retrigger() writes to the IMSIC MSI register to retrigger
an interrupt, but returns 0. The IRQ core treats zero as failure and
may schedule a software resend despite the hardware retrigger.
Return 1 after the MSI write to report successful hardware
retriggering and prevent the unnecessary software resend.
