drivers: imx: ipc: Add macro for interrupt_clear() on ARM64 

In the case of ARM64 with GIC, the interrupts are cleared after
the ISR is executed (for reference please see arm_gic_eoi() and
arch/arm64/core/isr_wrapper.S from Zephyr). Thanks to this, we
don't need to clear them explicitly, hence there's no need for
interrupt_clear() to be defined. This commit fixes linkage
problems caused by the fact that interrupt_clear() is not
defined on ARM64.
