imx: ventana: split out common functions between SPL and uboot
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) Signed-off-by: Tim Harvey <tharvey@gateworks.com>
