[PATCH 29/32] usb: dwc3: dwc3-qcom: Do not define 'struct acpi_device_id' when !CONFIG_ACPI

[Lee Jones]

Since ACPI_PTR() is used to NULLify the value when !CONFIG_ACPI,
struct dwc3_qcom_acpi_match becomes defined by unused.

Also need to place the platform data obtained via the matching process
inside the #ifdef, else that becomes unused too.

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

 drivers/usb/dwc3/dwc3-qcom.c:761:36: warning: âdwc3_qcom_acpi_matchâ defined but not used [-Wunused-const-variable=]
 761 | static const struct acpi_device_id dwc3_qcom_acpi_match[] = {
