filters: adrv9002: fix lte40 profile

The LTE 40 profile was showing a smaller BW as expected (which is 38MHz). The reason is because TES by default sets the Analog Low Pass Filter at 10MHz and it needs to be manually changed to 40MHz for the BW to be as bigger as expected. Signed-off-by: Nuno Sá <[email protected]>
