Input: imx_keypad - reset the hardware before enabling
Ensure the hardware is correctly initialized before requesting the interrupt, otherwise if a key was already touched since power-on the kernel enters an interrupt loop. To fix this issue we clear pending interrupt sources. We also have to make sure clk is enabled while changing the keypad registers.
