[PATCH v2] irqchip: Remove asmlinkage for *handle_irq() functions

[Jinjie Ruan]

Since commit 064dbfb41691 ("arm64: entry: convert IRQ+FIQ handlers to C"),
the gic_handle_irq() is only called by C functions.

And since commit a7b0872e964c ("irq: arm: perform irqentry in entry code"),
aic_handle(), aic5_handle(), clps711x_irqh(), davinci_cp_intc_handle_irq(),
ft010_irqchip_handle_irq(), ixp4xx_handle_irq(), omap_intc_handle_irq(),
sa1100_handle_irq() and fpga_handle_irq() are only called by C functions.

So remove the asmlinkages.

Fixes: 064dbfb41691 ("arm64: entry: convert IRQ+FIQ handlers to C")
Fixes: a7b0872e964c ("irq: arm: perform irqentry in entry code")
