arch/x86: Write ACPI DBG2 table only if the device has been enabled
The commit 93bbd41e (soc/intel: Enable ACPI DBG2 table generation) causes a crash on the mainboard mc_apl1. On this mainboard all internal SOC UARTs in the devicetree are switched off. As a result, no resources are allocated to the UARTs. The function find_resource() expects an existing resource. Otherwise, the CPU will stop. It should therefore not only be queried whether a device is present, but also whether it is enabled.
