Andy Shevchenko 4a5891992c ACPI: scan: Use unique number for instance_no
[ Upstream commit eb50aaf960 ]

The decrementation of acpi_device_bus_id->instance_no
in acpi_device_del() is incorrect, because it may cause
a duplicate instance number to be allocated next time
a device with the same acpi_device_bus_id is added.

Replace above mentioned approach by using IDA framework.

While at it, define the instance range to be [0, 4096).

Fixes: e49bd2dd5a ("ACPI: use PNPID:instance_no as bus_id of ACPI device")
Fixes: ca9dc8d42b ("ACPI / scan: Fix acpi_bus_id_list bookkeeping")
