mfd: cpcap: Fix interrupt to use level interrupt
I made a mistake assuming the device tree configuration for interrupt triggering was somehow passed to the SPI device but it's not. In the Motorola Linux kernel tree CPCAP PMIC is configured as a rising edge triggered interrupt, but then then it's interrupt handler keeps looping until the GPIO line goes down. So the CPCAP interrupt is clearly a level interrupt and not an edge interrupt. Earlier when I tried to configure it as level interrupt using the device tree, I did not account that the triggering only gets passed to the SPI core and it also needs to be specified in the CPCAP driver when we do devm_regmap_add_irq_chip().
