platform/x86: intel_cht_int33fe: Drop double check for ACPI companion device
acpi_dev_get_resources() does perform the NULL pointer check against ACPI companion device which is given as function parameter. Thus, there is no need to duplicate this check in the caller. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
