Change foootprint of ADA4622-4xCP to Analog_LFCSP-16-1EP_4x4mm_P0.65mm_EP2.35x2.35mm

The current footprint of ADA4622-4xCP is not exactly correct (exposed pad size slightly different).

This MR fixes this by changing the footprint do Analog_LFCSP-16-1EP_4x4mm_P0.65mm_EP2.35x2.35mm (kicad-footprints!xxx). It also fixes the description which contained a wrong package.
