Input: matrix-keypad - handle cases when GPIOs can't be wakeup sources
On certain boards not all GPIOs may be used as wakeup sources, in which
case some of enable_irq_wake() calls will fail. On resume calling
disable_irq_wake() will warn about unbalanced IRQ wake disable.
Solve this by checking whether enable_irq_wake() succeeded or not and
no not call disable_irq_wake() for these GPIOs/IRQs that have not been
enabled.
