nitrogen6x: update kernel configs

Previous kernel config changes are now merged upstream, and the fix
for the imx-vpu is also in, so all configuration changes can be removed.

Add support for Nitrogen6_Lite. The Nitrogen6_Lite board supports
a Broadcom 4331 WiFi/Bluetooth module, and typically has one of its'
GPIO ports configured as an LED_GPIO control (for a dry-contact output).
