MLK-12144 epdc: fix gpio active level to enable epdc signal

There's a GPIO pin to enable epdc signals on some platform like i.MX7D SDB.
However, it's changed from active-low to active-high on i.MX7D SDB RevB board.
Enhance the driver to handle the active level automatically,
then only need to adjust gpio as well as active level in dts file if necessary.
