irqchip/renesas-rzv2h: Replace single irq_chip with per-region irq_chip instances

Browse source

Replace the single rzv2h_icu_chip and its dispatcher callbacks with
dedicated irq_chip instances for each interrupt region: NMI, IRQ, and
TINT.

Move the irqd_is_level_type() check ahead of the scoped_guard in
rzv2h_icu_tint_eoi() and rzv2h_icu_irq_eoi() to avoid acquiring the
spinlock unnecessarily for level-type interrupts.

Drop the ICU_TINT_START guard from rzv2h_tint_irq_endisable() since it
is now only reachable via the TINT chip path.

[ tglx: Convert to hwirq_within() ]
