_acpi_{module,function}_name have no need to be (static) pointers to
static string literals - they can just be arrays, reducing memory
footprint. _acpi_module_name also can be 'const' qualified (requires
adding 'const' qualifiers to various functions' parameters), and
_acpi_function_name can be static (removing the code needed to
initialize the variable.
