ARM: msm: update GPIO chained IRQ handler to use entry/exit functions
This patch updates the MSM 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. Tested-and-reviewed-by: Abhijeet Dharmapurikar <adharmap@codeaurora.org> Acked-by: David Brown <davidb@codeaurora.org> Signed-off-by: Will Deacon <will.deacon@arm.com>
