Acer Extensa 5620Z: ACPI Battery detection problem

Tested build: PR #5719 / commit 3fe9e88 (artifacts from CI), reported per Fraizeraust's request.

Battery driver fails because of STATUS_ACPI_INVALID_DATA error:

(drivers\battery\battc\battc.c:348) QueryInformation failed (0xc014000f)

BatteryIoctl: Irp failed - c014000f

STATUS_ACPI_INVALID_DATA is returned by CmBattSendDownStreamIrp() because the OutputBuffer fields are all equal to 0, and its preceding IoCallDriver has failed with status 0xc0000034 (STATUS_OBJECT_NAME_NOT_FOUND).

Tracing into that call reveals that acpi.sys!Bus_PDO_EvalMethod is being called, attempting to evaluate ACPI battery method _BIF which then fails with AcpiStatus = 6 (AE_NOT_EXIST).

The actual failure happens somewhere in AcpiPsParseLoop() which gets called in a loop 6 times, returning following statuses:

• 0x4008 (AE_CODE_CONTROL | AE_TYPE)
• 0x4008 (AE_CODE_CONTROL | AE_TYPE)
• 0 (AE_OK)
• 0 (AE_OK)
• 0x4008 (AE_CODE_CONTROL | AE_TYPE)
• 6 (AE_NOT_EXIST)
