Since ACPI_PTR() is used to NULLify the value when !CONFIG_ACPI,
struct usb_xhci_acpi_match becomes defined by unused.

Fixes the following W=1 kernel build warning(s):

 drivers/usb/host/xhci-plat.c:457:36: warning: ‘usb_xhci_acpi_match’ defined but not used [-Wunused-const-variable=]
 457 | static const struct acpi_device_id usb_xhci_acpi_match[] = {
