ACPI / glue: Split dev_is_platform() out of module for wide use
There would be useful to have in future the similar API in platform core, as we have, for example, for PCI subsystem, to check if device belongs to it. Thus, split out conditional to a macro dev_is_platform() for wide use. No functional change intended. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Rafael J.
