Add device tree nodes for the WiFi and Bluetooth module mounted on the
VAR-SOM-MX93. The module can be based on either the NXP IW612 or IW611
chipset, depending on the configuration chosen by the customer.
Regardless of the chipset used, WiFi communicates over SDIO and Bluetooth
over UART.

The VAR-SOM-MX93 features Dual Freescale/NXP PCA9541 chip as a Power
Management Integrated circuit (PMIC).
The PMIC is programmable via the I2C interface and its associated
register map, and this patch adds its support.

The VAR-SOM-MX93 can integrate the WM8904, a high-performance
ultra-low-power stereo codec optimized for portable audio applications.
This patch adds the WM8904 device to the appropriate I2C bus, enables
the SAI peripheral, and introduces the sound node to expose the
sound card to the system.

The VAR-SOM-MX93 integrates an ADS7846 resistive touchscreen controller.
The controller is physically located on the SOM, and its signals are
routed to the SOM pins, allowing carrier boards to make use of it.
This patch adds the ADS7846 node and the appropriate SPI controller.
