mfd: max14577: Fix IRQ handling after resume if this is not a wakeup source
During suspend the IRQ should be disabled even if this is not a wakeup source. This is a proper way of fixing the IRQ handling issue during resume (IRQ handler fails because I2C bus did not resume yet). When device is suspended and max14577 interrupt is signaled the irq chip will try to handle it regardless of wakeup source. Device could be woken up by different IRQ but still the IRQ handler will try to read the registers over I2C bus and fail because I2C bus won't be ready yet: max14577 2-0025: Failed to read IRQ status: -5 Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
