APF9328 is an i.MXL based SOM (System On Module) that can be plugged on
several docking/development boards. Here only basic module support
is added (Ethernet, Serial, NOR Flash).

Changes since v3:
- suppress const and __initconst attributes for platform_data and
resource,
- add SOC_IMX1 in Kconfig
Changes since v2:
- add const and __initconst attributes for platform_data and resource,
- suppress boot_params.
Changes since v1:
- merge pins tables for UART
- suppress init/exit driver callbacks for UART
