drivers/{wifi/generic,intel/wifi}: Drop dependency on HAVE_ACPI_TABLES

This change drops the dependency of DRIVERS_WIFI_GENERIC on
HAVE_ACPI_TABLES as the driver provides operations other than the ACPI
support for WiFi devices. Since the dependency is now dropped, ACPI
operations in generic.c are guarded by CONFIG(HAVE_ACPI_TABLES).
