Move shared functions used by both SPL and U-Boot to common.c:
- setup_iomux_uart() and uart pad config
- gpio pad config
In the process also moved the following to common.c in preparation for
calling it from the SPL:
- split i2c setup into a shared function
- move pmic init to setup_pmic() function to call directly from
power_init_board()
- split gpio setup into early (iomux and default pin config)
and late (output configuration based on env)

Switch to an SPL image. The SPL for Ventana does the following:
- setup i2c and read the factory programmed EEPROM to obtain DRAM config
and model for board-specific calibration data
- configure DRAM per CPU/size/layout/devices/calibration
- load u-boot.img from NAND and jump to it
This allows for a single SPL+u-boot.img to replace the previous multiple boa
configurations.

Split the read_eeprom function out so that it can be shared (ie with SPL)

Gateworks Ventana is a product family based on the i.MX6. This
patch adds support for all boards in the Ventana family. Where
possible, data from the boards EEPROM is used to determine various
details about the board at runtime.
