memory: samsung: exynos5422-dmc: Add module param to control IRQ mode
The driver can operate in two modes relaying on devfreq monitoring mechanism which periodically checks the device status or it can use interrupts when they are provided by loaded Device Tree. The newly introduced module parameter can be used to choose between devfreq monitoring and internal interrupts without modifying the Device Tree. It also sets devfreq monitoring as default when the parameter is not set (also the case for default when the driver is not built as a module).
