[PATCH 1/3] mod_devicetable: helper macro for declaring oftree module device table




Little helper macro that declares an oftree module device table,
if CONFIG_OF is enabled. Otherwise it's just noop. Helpful for
reducing the number of #ifdef's.

Instead of:
    MODULE_DEVICE_TABLE(of, foo)
now use:
    MODULE_OF_TABLE(foo)
