MLK-13614 input: keyboard: imx: make sure keypad interrupts are enabled in suspend

Browse Source 
Change the suspend/resume callback to suspend_noirq/resume_noirq
callback to make sure keypad interrupts are enabled during suspend,
as when there is keypad interrupt coming after suspend callback
is called, the interrupt handler will still be called and it will
disable keypad interrupts, it will cause keypad can NOT generate
interrupts to wake up system from suspend.
