[PATCH v11 08/19] irqchip: gic: Remove spin locks from eoi_irq

This patch is motivated by the comment it removes from gic_init_fiq, namely that the spin locks in eoi_irq preclude certain platforms from supporting FIQ. Currently there is only one upstream platform (tegra) that actually hooks gic_arch_extn.irq_eoi and it does not require these spin locks.
