gpio/mxs: remove irq_high related implementation
The irq_high stuff was mistakenly copied from mxc gpio driver. The mxs gpio controller has only one irq line for each 32-pin gpio port. The patch remove irq_high related codes. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
