ARM: tegra: update GPIO chained IRQ handler to use entry/exit functions
This patch updates the Tegra gpio chained IRQ handler to use the chained IRQ enter/exit functions in order to function correctly on primary controllers with different methods of flow control. This is required for the GIC to move to fasteoi interrupt handling. Acked-by: Colin Cross <ccross@android.com> Signed-off-by: Will Deacon <will.deacon@arm.com>
