irqchip/renesas-rzv2h: Prevent TINT spurious interrupt
A spurious TINT interrupt is seen during boot on RZ/G3E SMARC EVK.
A glitch in the edge detection circuit can cause a spurious interrupt.
Clear the status flag after setting the ICU_TSSRk registers, which is
recommended in the hardware manual as a countermeasure.
