arm64: dts: imx93-11x11-frdm: enable additional devices

Enable additional devices on the i.MX93 FRDM board:

  - CAN port and associated transceiver
  - Bluetooth portion of the IW612 chipset
  - WiFi SDIO port
  - user buttons

The WiFi portion of the on-board IW612 chipset is still not supported
upstream, but since SDIO is a discoverable bus it will be probed once it
is.
