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.
