Subject: [PATCH v1 1/1] leds: nic78bx: tidy up ACPI ID table

Tidy up ACPI ID table:

- drop ACPI_PTR() and hence replace acpi.h with mod_devicetable.h and
  other necessary headers

- remove explicit driver_data initializer

- drop comma in the terminator entry

With that done, extend compile test coverage.
