[PATCH] Bluetooth: btintel_pcie: Add ACPI dependency

[PATCH] Bluetooth: btintel_pcie: Add ACPI dependency

[Venkat Rao Bagalkote]

The btintel_pcie driver uses ACPI functions (acpi_has_method,
ACPI_HANDLE, acpi_evaluate_dsm) in btintel_pcie_acpi_reset_method()
but can be built without CONFIG_ACPI, leading to build failures
discovered by IBM CI:

drivers/bluetooth/btintel_pcie.c:2309:14: error: implicit declaration
of function 'acpi_has_method' [-Werror=implicit-function-declaration]
 2309 |         if (!acpi_has_method(handle, "_PRR")) {
      |              ^~~~~~~~~~~~~~~

Add ACPI dependency to the Kconfig entry to prevent building this
driver when ACPI is disabled, since the driver requires ACPI
functionality for its reset method.

Hi Marcel and Luiz,

I'm submitting a fix for a build failure in the btintel_pcie driver when
CONFIG_ACPI is not set. Christophe Leroy helped identify that commit
912a499a7955 introduced this issue.

Good catch, I will fix it in place.
