imx: ventana: remove dependence on EECONFIG_SATA eeprom feature bit
The MSATA feature is a board-specific feature on Gateworks Ventana boards. In most cases a 2:1 mux will steer either PCIe or SATA to a miniPCIe socket through an MSATA_EN gpio. In these such cases assign the gpio in the board specific struct and use its presence to determine if we default the GPIO to PCIe and if we later steer it according to hwconfig.
