verdin-imx8mm/8mp: panel-cap-touch-10inch-dsi_overlay: use rising edge irqtoradex_5.15-2.2.x-imx
The touch controller generates a negative pulse of ~ 200us lenght.
The falling edge is a bit slower and noisier due to the used level
translation in HW. Change to trigger the interrupt on the rising edge
to lower the possibilty of triggering two interrupts due to noise.
