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 v5:
	- suppress array index for struct resource

Changes since v4:
	- use constant instead of multiplications
	- change maintainer description

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
